Chevrolet C2 buyer's guide

Overview

The C2 — the Sting Ray, 1963 to 1967 — is the Corvette as cultural treasure: the Bill Mitchell styling, the split-window coupe of 1963, independent rear suspension, disc brakes from 1965, and big-block power from 1965½ peaking in the 427 L88 of 1967. Two body styles, coupe and convertible, on a shortened, strengthened frame with the small-block (and later big-block) mounted well back. Every C2 is collectible; the market stratifies by engine, year and documentation with unusual precision, and rewards originality — matching numbers, original paint colours, honest cars — over mere shininess.

Generations and year breaks

1963 — the first Sting Ray

• The split rear window coupe: one year only, deliberately divisive then, an icon now. All 1963s are drum-braked; the Z06 competition package (big brakes, big tank) is the year's rarity.
• Fuel injection (the L84 327) topped the range — 360 hp and the most expensive option.

1964 — the refinement

• The split became a single pane, vents were tidied, ride and noise improved. Often the value buy of the generation precisely because it lacks the '63's mythology.
• Engines unchanged in essence (327 in four states of tune).

1965 — disc brakes and the big-block

• Four-wheel disc brakes became standard — the single biggest functional step of the generation.
• The 396 big-block (L78) arrived mid-year; the side exhaust became the era's signature option.
• Fuel injection's final year; the 327/375 FI car is a collector's high point.

1966–1967 — the 427 era

• The 427 in L36, L68, L71 (tri-power, solid lifters) and for 1967 the L88 — a racing engine in a street car, aluminium heads, 12.5:1 compression, no radio, no heater. An L88 is a seven-figure car and correspondingly faked.
• 1967 is the connoisseur's pick: the cleanest detailing, five-slot fender vents, and the last of the line.
• The L89 aluminium-head option on the L71 is rarer still and equally documentation-bound.

Engines and options that matter

• 327 small-blocks (250–375 hp) — the correct heart of most C2s. The solid-lifter L76 and fuelie L84 are the premium small-blocks.
• 396 (1965) and 427 (1966–67) — the big-blocks step the price up; the L71 tri-power is the realistic summit, the L88 the legend.
• Four-speed manuals dominate the valuable cars; Powerglides are a deduction except in mild small-blocks. The M22 Rock Crusher (1966–67) is rare and coded on the case.
• Factory air conditioning in a big-block convertible is a value combination; in coupes it adds comfort value. Side pipes, knock-off wheels (bolt-ons from 1964) and teak steering wheels are often added — price them as accessories, not originality, unless the tank sticker says so.

What to check before buying

• The birdcage: the steel structure inside the fibreglass around the windshield and under the body rusts, invisibly, and is the C2's fatal flaw. Inspect the windshield frame corners, the door pillars and the area under the glovebox; ask for photos of the frame and birdcage on any serious purchase.
• Frame: the kick-up over the rear suspension and the front crossmember rot; original frames carry a partial VIN stamping on the top of the left rear rail — hard to see, decisive when visible.
• Numbers matching, defined: the engine pad should carry the VIN derivative and the correct suffix for the claimed specification; the transmission and rear axle carry date/stamp codes. On a big-block or fuelie car, pay for expert verification — the premium for "matching" is large and so is the fraud.
• Tank sticker: from 1967 (and rarely earlier), the build sheet glued to the fuel tank lists every option. Its survival transforms a car's documentation.
• Fibreglass repairs: look from underneath for patches and replaced panels; front-end damage is common and a one-piece replacement nose, while serviceable, is a deduction on a top car.
• Trailing arms/rear bearings: as per all early Corvettes, the rear suspension's service history is the maintenance question that matters most.
• Parts: excellent reproduction support for everything serviceable; dated, correct components for high-spec cars (distributors, alternators, FI units) are the expensive hunt.
