3. Saleen S7
Saleen S7 is a hand-made vehicle, which makes this supercar even more spectacular. But just like some other models on the list, this model comes in limited numbers. The engine that was initially used produced 550 ponies, whereas, in 2005, the S7 received a new powerplant that delivers 750 hp. This allows the S7 to reach 248 mph and accelerate to 60 mph in 2.8 seconds. Astonishing!
