Ford Thunderbird Turbo Coupe
The Turbo Coupe is one of the most underrated American cars produced, period. As a direct result, it’s also dirt cheap. A quick recap: underneath its entry-level luxury sports coupe facade, it’s basically a Mustang SVO, which is anything but unappreciated today.
Chevrolet C4 Corvette
How can a Corvette be underrated? Well, 1) because it doesn’t have the «classic» look of its two immediate predecessors, and 2) it doesn’t have the blazing speed of its successors (especially true for the first couple years of production).
In a very real way, though, it’s the missing link that connects the modern Corvette with its ancestry. Right now, you can find the odd C4 Corvette for under $5k — but you had better believe that value is on the up and up.
