After owning the car for a couple of years. Here is a review that might be useful to some. Having driven both engines Ls2 and Ls6. I would say that Ls6 is a tick faster on the top end. The car is Daily driver and is good fun as an American car can be. After owning several GM built cars over the years, I will now consider another brand just because competitors have built superior cars. V is not very thought out. The shifter is terrible - too much effort. The suspension is not forgiving. This car is not on the same level as the AMG and M5. They are fast and comfortable and driver feels connected to the car. with this, it feels like you are in a substandard product.
It is fast car but not a driver's car. Yea the new Cts v has 556 HP , but it will be a pile of junk after 2-3 years with lots of rattles and squeaks and cheap interior materials breaking. I will say this , that you get what you pay for and with this caddy you pay less $ than an E55 or an M5.
GM , you need to build cars with higher quality and less rattles. I just recently test drove a new LS3 corvette and try to give you guys a second chance. As soon as I sat in the car I knew I wasn't buying this awful interior. You may get lots of ignorant buyers who haven't driven a proper car.
