the complaints on sound are more about road noise and primarily the way the exhaust sounds... not deep and throaty or porsche-racy, but instead just a notch better than outgoing 350s... not my opinion at all, I think with some HFCs and cat-back it sounds great... suggest you check the exhaust sound clips thread and hear for yourself
as for coupe or roadster... dude, you're in ohio ! lol coupe
+ better for enjoying the great tracks in your area
