Im surprised you all are actually saying the Cruze would be cheaper to insure. Granted Im 30, but I did a quote just for the hell of it and if I traded my SS in, my insurance would go UP with the Cruze. Not sure how that works, but Id go to a dealer, pull VINs from a Cruze and a Camaro, and give them to your agent for a quote. Thats going to be your best bet. Id say go with the Camaro. I dont know about you, but I hated having people in my backseat. So I always had sports cars and told my friends, Oh sorry, no room for you. But Im 6'2', and need the leg room.
Good luck man!
