I like them both in a different way, T-tops are sweet on the Camaros, I wouldn't buy a Camaro with out them. I wish the Mustangs still had them . In the Camaro you feel like your sitting lower to the ground, this can be a good or bad thing depending on what you like. I feel like your sitting up higher in the Mustang. IRS is nice on the Cobras. I like both cars a lot, they both have there ups and downs. There are little things I like and dislike in both. After owning both LT1 and LS1 Camaro, I wouln't buy a Mustang slower than a Mach 1.
