2004 Saleen S7

The 2004 Saleen S7 is a hand-built, high-performance American supercar. The heart of this beast is a naturally aspirated 7.0L (427 cu in) Ford 351 Windsor-derived V8 engine producing 550 horsepower and 525 lb-ft of torque. This engine is mated to a 6-speed manual transmission. Owners often rave about the S7’s striking design, incredible performance, and exclusivity. However, some common criticisms include its harsh ride, limited practicality, and high maintenance costs, characteristic of a low-volume, high-performance vehicle.
