2. Buick GNX
The 1987 Buick GNX is the very definition of a sleeper, wearing the conservative skin of a Regal coupe but packing a ferocious turbocharged V6 under the hood.
Pumping out 276 horsepower, it was notorious for outrunning even the mighty Corvettes and Ferraris of its day.
Its stealthy, understated appearance gave no warning about the thunderous acceleration lurking within, making it a legend among muscle car enthusiasts.
The GNX’s blend of brute force and subtlety remains unmatched, earning it a permanent place in automotive history.
