Chevrolet Corvette C3

Overview

Produced from 1968 to 1982, the C3 Corvette featured the distinctive 'shark' styling with longer bodywork, T-top removable roof panels, and improved aerodynamics. It was the longest-running Corvette generation and included both coupe and convertible body styles, with various performance-oriented trims and engine options. The C3 saw the introduction of higher-displacement V8 engines and refinements to interior comfort and technology, making it a true classic and a symbol of American muscle and style.

Owning One

Why collectors want it

Mako Shark II styling; the chrome-bumper 1968-72 big-blocks are the desirable end before emissions strangled output. The long run makes it the accessible vintage Corvette.

Which one to look for

L88/ZL1 427 ('68-69 grails), LT-1 solid-lifter 350 ('70-72), 454 LS5, '78 Pace Car / Silver Anniversary, '82 Collector Edition (first hatch glass, end of line).

What owning one is like

Birdcage/frame rust at the rear kick-up and windshield surround, fiberglass stress cracks, pop-up headlight vacuum actuators, sagging doors, T-top leaks, tired smog-era engines.
