C4 crap box kick around...

Any Corvette in the condition described as above is can be expensive to restore or at least get into proper mechanical condition. The early eighties Corvettes are the least expensive, desirable and the Crossfire engine could be problematic.
Corvette prices are all over the map and condition and records mean everything
Id personally stay away from any beat low priced Corvette as well as used Corvette's on dealership lots
There are enough adult owned C4 and C5 Corvettes that were pampered and always garaged, good clean low milage cars available
That being said those C4 and C5 Corvettes are a great car for the money if in good condition
