I found a 2008 CTS AWD with Performance, Luxury 1, and Luxury 2 packages. I had them send me the build sheet and it states that it has the 3.6L VVT (LY7) engine. I did not know they made the "loaded" CTS in AWD without the DI engine. Can anyone provide any insight on this. Also, how is the VVT engine? I realize it is 263 hp vs the 304 hp on the DI, but will it seem doggy?
