The STS has 300 horsepower, not 3000 :shocked2: - at least until the quad turbo Sixteen engine goes in.simo said:
The SLS (Seville Luxury Sedan) has lower horespower but slightly higher torque than the STS (Seville Touring Sedan), a smaller ratio rear axle, and a softer suspension. That's about it, except some '02 and all '03 STS's have the Magnetic Ride suspension while none of the SLS's do. The bodies are identical. Early STS/SLS had slightly different bodies than the more recent ones (changed in mid to late 90's?).
