The biggest issue will be trim as it is unique to the vehicle. Fortunately, the inherent quality of those bits is high and I've never seen a better paint job. Even my friend's first year Audi TT convertible has more orange peel to the paint surface. Go to an old car meet and see if you can find anyone with an old Packard and they will tell you that many have survived over the years because the original engineering and manufacturing quality was so high. In many ways Packard and Mercedes both build their reputations from over-engineering their products rather than a lot of companies that built to a price.

The good part is that the major mechanical parts of the Crossfire can be found amongst many past, current, and future Mercedes models. Indeed the 3.2 motor has been one of their most prolific and successful engines to date.

As for $120 oil changes, one can learn to do it easily. The engineers wisely put the oil filter in a very accessible location. Now tires are expensive, depending on what and from whom you buy, but I just got four Kumho Ecsta SPTs for $704 out the door in Charleston SC. Though not a "luxury" brand tire, to be honest, in most of the reviews I read online, the Kumhos did better than many others like Continental's, Bridgestones, Etc. In PA I was getting quotes on various tires ranging from $960 to $1100. Like anything just shop around and it will save you some pain in the bank account.
