This is what I found on the saleen:
Saleen S281 4.6L 2V producing 445 Horsepower and 450 ft lbs. torque
0-60: 4.61 sec.
1/4 Mile:
[email protected]
60-0: 126ft.
Slalom: 68.87
Top Speed Around 185 mph
However it is taged with a price of 61,120.00 for the coupe.
A cobra would be alot better if you want to put money into it. With the money you spent on the saleen, you could buy a cobra and ALOT of parts for the car to outpass the saleen. However some do not want to deal with the hassle of building a car (I find it to be the fun part) so they want an already fast stock car. In that case, the saleen is your best shot.
