I've owned and wrenched on my share of Corvettes. Whether old or brand new, they are all extremely finicky and nothing is cheap when it breaks on them.

If you want a project car that needs constant attention, go ahead. But if you are looking for something even remotely reliable, stay far, far away. 

• These were the years that Corvettes were low horsepower and older technology.  Anything this old should be bought on a case by case basis. They will never make a daily driver out of one but they can be fun as a weekend toy. With a car of that age there will be things to repair often.

These Corvettes were made out of fiberglass and were primarily Chevrolet 350 and 454 engines. A couple oddities to look out for are the flip-up headlights: If the vacuum system that controls them is not functioning it can be costly to repairs and difficult to source parts. Also look out for rust - the body might be rust free but the frames are often rusted badly due to age and prolonged exposure to the outdoors. I would also take a look at the rear end "gear box" assembly. Chevrolet introduced this gearbox style rear end and only used it on the Corvette. Same situation as the flip up headlights: it can be expensive to repair and difficult to source parts.
