Thanks guys,

The M5 is a total beast (it's my father's car), and we probably shouldn't compare to it here. I've actually considered getting one, but I'm really looking for a convertible. Unfortunately the roadster equivalent Z8 is a bit out of my price range.

A lot is going to depend on how much money I have. With the exception of a few jobs I don't really get paystubs, so it's not too easy for me to get a loan. Most likely I'm paying with cash. Currently, the crossfire is right at my price point. How much I spend/earn before march will ultimately decide which car I go for. The crossfire has definitely grown on me though.

So besides CAI, sprint booster, and dyno there really isn't much to do? What about exhaust?
