I'm just a car guy. I don't have any allegiance to any particular brand however, I lusted after Corvettes since I was 12. I have owned two C6's an 07 and 08 (both manuals.) So it's not that I'm against Chevy but the Camaro just looks and feels HUGE to me. The 2013 5.0 doesn't pull as strong as my Vette did but it's still a pretty impressive car. I think the interior materials could use a little help but otherwise I like it a lot better than the Camaro.
I can appreciate the OP's decision to trade the Mustang and that's why they make different cars. I hope you have fun with it and if you're happy that's all that matters.
