First off, I am biased, I love mine as much as Jones loves his Audis. However, that being said, I would drive a G8 but really wanted a manual tranny and did not feel like looking for the GXP unicorn. The CTSv is a considerably smaller car. As far as reliability, there are a couple of common issues on a v...motor mounts, differential bushing, and the "weak" rear end. The rear end will asplode with wheel hop. If you want a drag car neither will fit the bill well in my mind. The v strikes a great balance between good ride and good handling. They are not simple to lower due to the auto leveling shocks on the rear but, in my mind, they sit pretty low stock (shut up farkas). Long and short of it, I don't think you can go wrong.
