In that case, I'd take the STS-V. The 1st Gen CTS-V is a beast and compared to the STS is unrefined, but tons of fun. It also has a bad axle hop, plus it only comes in a stick shift, and has a harsh ride and a substandard interior. But for overall performance, the 1st Gen CTS-V is a a bargain.

CTS-V used two different kinds of engine; the '04-'05 used an LS6, while the '06-'07 had an LS2. The STS-V uses a Supercharged 4.4L Northstar with 469 horsepower.
