I looked into the Challenger Hellcat and the Charger, but found that due to limited production you cant get one for MSRP. They are really heavy and aren't going to handle like an ATS-V, and in the 4 door you can't get a manual (may not be an issue for you but was for me). After months of looking at and researching various cars it came down to a list of 4 - used Jaguar F-type v8s (most beautiful of the bunch but auto only and used) A C7 corvette, an M3 and last but not least the ats-v. BMW lost the chance of getting my business because they are a bunch of pricks. The Corvette was the most fun to drive and the Jag gave me wood every time I looked at it. Then I checked out the Caddy and felt an immediate bond with it. To me it is a 4 door Corvette that is more luxurious and the back seats can actually fit adults in the back when needed. GMC has the best shock absorbers hands down to giive the best of both worlds, good handling and a pretty decent ride for how well it handles. The M3 felt stiffer and more bouncy in comparison. Finally by going through Costco I was able to get a good deal on the ATS-V. I love the car and am very happy with my decision. Just can't wait now to finish breaking it in
