First, I own a 2005 CTS-V, essentially this means my 400HP comes from a 5.7 L Aluminum block instead of a 6.0 L one..that difference notwithstanding, the vehicles are nearly identical. First, this is an amazing vehicle, and can be had at a reasonable price. I purchased mine and it still has a full MasterGuard GMPP Warranty. For those of you who are looking at CTS-V's, I would recommend post 2005, as the 05's have rear differential issues that were addressed with an updated P/N in 06 (mine has been replaced). I get many positive comments on my black V, and she begs to be driven rough. The 6 speed is phenomenal, if a little bulky in traffic. Very smooth, very dignified, and fits the family
6-speed, Built in G-Meter, 400 HP small block, Brembo Brakes
This is a purist Caddy (if there is such a thing) but I agree with others that some features (HUD, push button) would be welcomed which they've addressed in the '09. a GM supported supercharger kit would be fantastic. back it with a warranty and people will strap another booster on this rocket ship.
