Monteverdi High Speed 375

Overview

Peter Monteverdi lost the Ferrari franchise for Switzerland in 1963, when Enzo demanded payment up front for a shipment of a hundred cars and Monteverdi refused. Four years later he answered with a GT of his own, built in the family workshop in Binningen on the edge of Basel. The High Speed 375 appeared at the Frankfurt show in September 1967: a box frame of square steel tubes made by a local structural-steel firm, double wishbones at the front, a de Dion axle at the back, discs all round, and a 7.2-litre Chrysler 440 Magnum bought off the shelf.

What followed over nine years was not one car but a range. Pietro Frua bodied the first two-seaters in alloy. After a lawsuit ended that partnership, Carrozzeria Fissore built a squarer body, and the longer 375 L 2+2 became the car Monteverdi actually sold. Around it came a short-wheelbase coupe, a convertible, and the 375/4, a five-metre four-door saloon the factory aimed at the Silver Shadow and the Mercedes 600. Roughly 160 cars of all types were built across the whole run. Nobody, the factory included, kept records good enough to be certain.

Fully analogHeavily electronic

Fully mechanical. A single four-barrel carburettor on the 440 Magnum cars, breaker points and a condenser in the distributor, a mechanical fuel pump, and a hydraulically controlled TorqueFlite. Nothing measures anything, and nothing decides anything on the driver's behalf. The only electrical complication is comfort equipment, which on a 375/4 could run to air conditioning, power windows and a factory-fitted Sony television. One caveat applies to late cars: Chrysler made transistorised ignition standard across its own range for 1973, so a 1973 to 1976 Monteverdi may have arrived with a magnetic pickup in the distributor and a control box governing spark timing. That is one solid-state system in an otherwise wholly analog car.

Values have moved hard since the mid-2010s in a market so thin it barely registers: classic.com lists none for sale and four sold in five years. A one-owner 1971 Geneva show 375 L made $210,112 in September 2016, a right-hand-drive car made £57,500 at Bonhams London in December 2017, and a Frua-bodied 375 S made CHF 230,000 at Gstaad in July 2022. Restoration-fresh dealer cars now ask far above any of those. Rarity is doing most of the work, helped by a broader rediscovery of European GTs with American engines. The band below describes the Fissore 375 L 2+2, not the Frua cars.

Buyer's guide

What anyone seriously considering this car should know first.

Why it's worth it
Switzerland's only series-production luxury GT, hand-built outside Basel around Chrysler V8s
Callout
Named for the Chrysler 440's 375hp SAE gross rating, a figure the DIN standard cut by about a third
What to watch for
Provenance is the whole game here, because Monteverdi's own paperwork will not save you. The factory kept inconsistent records and no two published production counts agree, so a car's history file, its chassis number and its standing with the Monteverdi Club matter far more than they would on a marque with a proper build-sheet system. Establish which shop built the body. Frua cars are alloy and carry a large premium. Fissore cars are steel, and a handful were bodied instead by Poccardi or Embo to the same design, which is genuine rather than suspect. So are the Frua-shaped bodies that Fissore built after the split; the last of those were still being sold off in 1973. Then look at the body itself. Every panel, every piece of glass and every strip of brightwork was formed by hand in tiny numbers, so accident damage or serious rot becomes a fabrication project rather than a parts order. Underneath, the square-tube frame is simple and the Chrysler drivetrain is the least of your worries. Buy the straightest, most complete car you can find and accept a list of mechanical jobs. The opposite trade costs several times as much.

The Story

Driving character

The 375 makes its case on the first fast road you find and keeps making it until the fuel runs out. Chrysler rated the 440 Magnum at 375hp and 480lb-ft at 3,200rpm, and even after the DIN standard cuts that by roughly a third, the car simply leaves. No downshift, no drama, none of the theatre a Ferrari would demand for the same result. Auto Motor und Sport timed a 7.2-litre 375 L at 229.3km/h and 8.2 seconds to 100km/h in spring 1972, against a factory claim of 245 to 260km/h and 6.5 seconds. That gap is the honest story of the car, and by 1974 the emissions-strangled engines had pulled the real figures down further still. At 1,820kg the 2+2 is heavy, but the de Dion rear axle with its Watt linkage and coil springs gives it much better manners over bad surfaces than the mass suggests. The ZF worm steering is slow and needs learning. The transmission tunnel is enormous and the pedal box is tight. In exchange you get a car that crosses a continent quickly and arrives unbothered.

Design

Frua's original is the beautiful one, and it belongs to a family. The same pen drew the Maserati Mistral and the AC 428, and the resemblance is close enough that sources have long claimed the three share glass and door pressings, which is worth treating as a claim rather than a fact. Monteverdi's own literature credited the shape to Peter Monteverdi rather than to Frua, and that is roughly where the royalty dispute began. The 1969 Fissore body kept the Frua proportions almost exactly and squared off both ends, which reads as a coarsening or a modernisation depending on your eye. What is not in dispute is the parts-bin economy under the elegance. Tail lights on the 375 L and early 375/4 are Alfa Romeo Giulia Berlina units. The 375/4's door handles come from a Fiat 128, late cars switched to Triumph TR6 lamps, and one very late saloon left with rectangular Ford Granada headlights and rubber-faced bumpers. Inside, the dashboard was English in spirit until 1972 or 1973, wood and round dials, then turned black and sporting.

Motorsport pedigree

There is none, and the reason is a law. Switzerland banned circuit racing outright after the 1955 Le Mans disaster, and that ban stood until the federal government lifted it with effect from 1 July 2026. A Swiss constructor in 1967 had no home circuit, no domestic series and no reason on earth to build a homologation car. Peter Monteverdi had done his racing already. Formula Junior and hillclimbs through the late 1950s, then his own MBM single-seaters from 1960, and one Formula One appearance at the non-championship 1961 Solitude Grand Prix, where he retired after two laps. He withdrew his German Grand Prix entry after being injured and stopped driving. So the 375 never turned a competitive wheel, though its engine did plenty of racing without it: the Chrysler 440 was a NASCAR and drag-strip staple in America while Monteverdi was bolting it into hand-formed Italian bodywork. He came back to the sport at the far end of his career, buying the Onyx Formula One team in 1989, whose best result was Stefan Johansson's third place at that year's Portuguese Grand Prix.

In culture

The Monteverdi's cultural footprint is small, specific and a little odd. A 375 L appears in Zeta One, a 1969 British spy spoof, supplied by the factory and credited on screen to Monteverdi Concessionaires Limited. That is essentially the entire screen record for the marque. What Monteverdi had instead was a customer list. American buyers took a share of the output, and the Middle East took more, with the Qatari royal family among the 375/4 owners. When car production stopped, Peter Monteverdi turned the Binningen factory into the Monteverdi Car Collection, which opened in 1985 and closed in 2016; most of the cars went to the Swiss Museum of Transport in Lucerne, which is where a visitor is now most likely to meet one. Jay Leno owned one of the six Fissore-bodied short-wheelbase coupes for several years, which did more for the marque's profile in America than the factory ever managed. Beyond that, the 375 is a car for people who already know. Nobody buys one to be recognised at a show.

Owning One

Why collectors want it

Scarcity is the obvious argument and it is a real one: whichever count you accept, this is a car most collectors have never stood next to. The better argument is what the scarcity bought. The 375 is the only series-production luxury car Switzerland has ever managed, and its range covered ground no other small maker attempted all at once, from a Frua two-seater to a five-metre saloon pitched at Rolls-Royce.

The hierarchy is steep and well understood by the few people who follow it. The sixteen 375 S coupes sit at the top, ten of them alloy-bodied by Frua and closely related in the metal to the Maserati Mistral and the AC 428 that came off the same drawing board. One of those, a Geneva and New York show car, made CHF 230,000 at Bonhams in Gstaad in July 2022.

Below them the Fissore 375 L 2+2 is the car a buyer will actually find, and the one whose values have climbed hardest since the mid-2010s. The 375/4 saloon is the connoisseur's pick and the hardest to place, because only a few dozen exist and almost nobody is hunting for one. None of it is liquid, in either direction.

Which one to look for

Start with the split, because it divides the whole run. The 1967 to 1969 cars wear Pietro Frua's alloy body. Frua built ten of them before Peter Monteverdi refused to pay royalties and Frua obtained a court order stopping further use of the design. Fissore built six more to that same Frua shape before it had to stop, which makes sixteen 375 S coupes in total and explains why the market chases them. From 1969 the Fissore body took over, squarer at both ends, and the long-wheelbase 375 L 2+2 became the volume car. That is the one to look for if you intend to use it: two usable rear seats, air conditioning, and around a hundred built by the club's count. The short-wheelbase Fissore two-seater is the connoisseur's pick at six cars. The 375 C convertible carries the best story, reportedly built at the request of a paraplegic friend of Monteverdi's who wanted a car he could get into unaided, and sources record either two or six. The 375/4 saloon, around thirty-five of them, is the strangest and the most Monteverdi thing here.

High Speed 375 C · 1971

The only convertible in the 375 range, derived from the short-wheelbase 375 S and shown in yellow at the Geneva Motor Show in March 1971 at 75,750 Swiss francs. It used the Alfa Romeo Giulia tail lights of the 375 L rather than the coupe's six round units. Period reporting found it short of rigidity. The literature repeatedly records that the car was built at the request of a paraplegic friend of Peter Monteverdi who wanted a Monteverdi he could get into unaided.

High Speed 375 L (Fissore) · 1969–1976

The volume model and the car most buyers will actually encounter. After the split with Frua, Monteverdi reworked the range around a 2+2 on a 2,680mm wheelbase, because that is what enquiries told him people wanted. The new Fissore body held Frua's proportions almost exactly but squared off the nose and tail, with chrome-ringed twin round headlamps and Alfa Romeo Giulia Berlina tail lights. Kerb weight is 1,820 to 1,840kg. Auto Motor und Sport recorded 229.3km/h and 8.2 seconds to 100km/h in spring 1972. The dashboard changed from wood and round dials to black velour for 1972 or 1973.

High Speed 375 L (Frua) · 1968

A one-off. Frua stretched the 375 S into a 2+2 with a substantially reworked side profile and roof, shown publicly in 1968. It stayed at the factory and was never offered for sale. A second Frua-built 2+2 body was retained by the coachbuilder and sold on to AC in 1971, where minor changes including part-covered headlamps turned it into the one-off AC 429.

High Speed 375 S (Fissore) · 1969–1971

The short-chassis two-seater rebodied in the Fissore idiom, aimed at sportier drivers and offered with a manual gearbox option. Recessed headlamps and six round tail lights set it apart from the 2+2. It sold far worse than the 375 L, which is exactly why it is now the connoisseur's choice. In the winter of 1971 and 1972 it was developed into the Monteverdi Berlinetta, with a stiffened tubular frame and a slim full-width grille, sold under its own name rather than as a 375.

High Speed 375 S (Frua) · 1967–1969

The car that started it, shown at the Frankfurt IAA in September 1967 on the Auto Becker stand. A two-seat coupe on a 2,510mm wheelbase with an alloy body designed and hand-built by Pietro Frua in Turin, closely related in the metal to his Maserati Mistral and AC 428. Monteverdi's men fitted the drivetrain in Binningen, the rolling chassis went to Turin to be bodied, and the finished car came back to Switzerland for delivery. The most valuable version of the car by a wide margin.

High Speed 375/4 · 1971–1976

The strangest thing Monteverdi built and the top of the range. A four-door saloon on a 3,180mm wheelbase and 5,310mm long, carrying the 375 L front end to the A-pillar and then four wide-opening doors with Fiat 128 handles. Full leather, air conditioning and electric windows as standard, with an optional Sony television, a bar and a partition between driver and passengers. The factory pitched it directly at the Rolls-Royce Silver Shadow and the Mercedes-Benz 600. Details changed constantly: Alfa Giulia tail lights gave way to Triumph TR6 units, and one very late car left with rectangular Ford Granada headlamps, a matt black grille and rubber-faced bumpers.

What owning one is like

Two entirely different cars live under one badge, and they age at different rates. The Chrysler half is the easy one. A 440 Magnum, a TorqueFlite and a Salisbury-based rear end are among the best understood components of the era, and a competent shop anywhere can rebuild all three. Monteverdi added a bigger seven-litre oil pan and an oil cooler, plus a transmission cooler on automatics, and otherwise left the engine alone, so there are no bespoke internals to chase. The Swiss and Italian half is where the time goes. Bodies are steel over a square-tube steel frame on everything except the Frua cars, formed by hand in tiny numbers, with no panel supply of any kind. Early Fissore-era cars had teething trouble with fuel systems, brakes and throttle linkages as production moved between shops, and the 375 C convertible was reported at the time to lack rigidity. Reckon on 18 to 23 litres per 100 kilometres, which is the factory's own figure. Plan the route around fuel stops and the car is genuinely usable.

Upkeep & parts

Budget in two currencies. Anything Chrysler supplied is cheap and everywhere: the 440 Magnum, the TorqueFlite, the ignition, the fuel and cooling hardware, all of it carried by the same enormous American aftermarket that keeps Chargers and Road Runners running, none of it needing a specialist.

Anything Monteverdi or Fissore made is a fabrication job. There is no reproduction panel, no window glass on a shelf, no interior trim kit. Some of the small parts are easier than they look, though, because Monteverdi shopped where everyone else did: Alfa Romeo Giulia Berlina tail lights on most cars, Triumph TR6 units on late ones, Fiat 128 door handles on the saloon. Brakes are Girling, front suspension components came from Alford and Alder, and the steering is ZF, so the chassis hardware has British and German parentage that helps enormously.

The Monteverdi Club, founded in Binningen in 1985, is the single most useful thing an owner can join, because it holds the closest thing to a production record that exists. Expect to wait for parts, and expect to make some.
