my dad has the 06 SL 500 and it is hotttt, it's sooo fasttt i test driven it on a highway WOW and he has no idea i test drove it because i refilled the gas. HAHAHA. my mom drives an 05 sc430, and i drive it sometimes too (rarely). i love that car too. but my fav is the bmw 6 series which we don't have. is the 6 serious better than any of the other two, why? which of the 3 is your favorite and why?
