18: Chevy Corvette C4
When it comes to underrated performance cars the Corvette C4 is about as underrated as you can get. This was the generation right before the C5 and for most enthusiasts, it was considered outdated. But the C4 shouldn’t be overlooked, as this is one of the best generations for the Corvette brand. This was one of the first Corvette models to use a fuel-injected engine, and there are various specialty models made throughout this time (via Car Survey).
The C4 Corvette model was the precursor to the C5 platform, which was one of the most popular Corvette models of all time. The last model years for the C4 were the best, and the car is as close to a modern Corvette as you can get for the price range. Between the design characteristics and the performance, the C4 is one of the best bargains in the Corvette world.
