1988 Chevrolet Corvette: Buy or Avoid?
The 1988 Chevrolet Corvette offers an exhilarating, raw American sports car experience for enthusiasts, but it demands careful consideration and a dedicated owner. While the L98 V8 engine is largely robust, expect to contend with various electrical gremlins and unique maintenance challenges inherent to its C4 generation.

Be prepared to address its well-documented electrical issues and the notorious 4+3 manual overdrive unit. A thorough pre-purchase inspection and a realistic budget for pote…
