Pre-purchase walkaround
1971 Chevrolet Corvette (C3)
82,000 miles · asking $30,500
Five-year cost to own, maintenance and fuel
~$6,200
The 1972 C3 is a chrome-bumper (front only) small-block or big-block sports car with a fiberglass body over a steel birdcage frame. Money goes into rust in the hidden steel structure, worn front suspension, and sorting out decades of amateur work, not the engine itself which is cheap and simple.

What to look for on this one
Every used example of this chassis has the same questions. The bands show when each tends to surface; the gold line is this car at 82,000 miles.
Worn front suspension and steering$660-$1,800 if not done

Ball joints, tie rod ends, idler arm, and control arm bushings wear out and are often neglected on cars driven little. The recirculating-ball steering box also develops slop. Wandering, clunks over bumps, vague steering, uneven front tire wear.
Frame and birdcage rustpriced only if found
Condition-driven, not mileage-driven, so it is not in the totals and inspection is the only answer. Doors that don't align, sagging body, rust bubbling near the windshield A-pillars and rear kick-up areas.

Hand this to your inspector
A $300 inspection against this list is the best money in the whole deal.
01Get the car on a lift and inspect the rear frame kick-ups over the axle and the front A-pillar birdcage for rust perforation.
02Poke the body mounts and their steel cups with a screwdriver to check for rot and confirm the body isn't sagging onto the frame.
03Check all four gaps around the doors and hood; misalignment signals frame, mount, or crash damage.
04Operate the hidden headlights and wiper door several times to confirm the vacuum actuators cycle fully.
