speaking of hella expensive and audi: R8. wow in every way.
i agree - corvettes rock, and surprisingly insurance is cheaper than that of a mustang or camaro. at least, that was a year or so ago when i looked into it (GM discount and all

).
i have to say my favorite GM cars out now are the new cadillac CTS and STS. they look wicked, have incredible performance, and cadillac has one of the highest customer service ratings in all the classes.
