I've owned my 04 since it was brand new, so I thought I'd chime in.
Many times over the years I've heard comments from various people suggesting that it may be in your best interests to stay away from purchasing the 04 Crossfire. I never appreciated hearing that, but usually chose to simply ignor it.
Maybe it's because they had the most TSB's sent out about them, which I feel is pretty normal for any 1st. year model. On the plus side, I don't think Chrysler/Karmann changed any of it's original parts designs over the years, so maybe it just took some time for the assembly line to get their act together. At any rate, by now, any problems that may have turned up in the premier model has more than likely been taken care of years ago.
My 04 has nearly 55k miles on it, with only a rear hatch vacuum hose leak fixed under warranty (Which I understand is common in several years) and they replaced my battery under warranty as well.
Just look for the best example you can find for the money that you're willing to spend.
Good Luck
