Re: newly interested in crossfires and need to learn
Parts are not hard to find if you need engine parts, filters, hoses, etc as so much is shared with the SLK320 and other 3.2L Mercedes-powered vehicles. Chassis (brakes, rotors, flex discs, etc.) are also shared with the '320 and are not an issue - but body parts and some interior parts are hard to find and often, you are at "Pick a part" or some salvage yard when it comes to such items.
As to finding someone to work on it, I think that, in a way, we overblow that 'crisis'. If you stay the hell away from Chrysler dealers, things are not so bad. Any competent shop can do brakes and fluids (if you provide the fluids, otherwise, expect the shop to screw that up).
If you run into electrical/electronic issues, well, the only reason other dealers can fix those issues is due to good factory support - the Crossfire is without factory support and dealers are helpless, so such problems can cost thousands at any dealer or shop - but the assembled brain trust here can usually handle any issue that comes up. Again, it is best to ask here before you take the car anywhere for anything beyond oil changes or brake jobs.
If you simply are not interested in working on the car yourself, and depend on those you must pay for service, the car is going to cost you a lot to maintain - but, say, a Nissan Ultima would also cost you a lot so who cares?
Speaking of oil changes, the Crossfire is the first car (that is CAR) in 42 years of driving that I can change the oil on without jacking the car up. I have a 2 1/2 gallon low profile drain pan I use - and filter changes are done from the top (unlike any car I've owned). Alternator replacement is also easy, as is changing the water pump, idler, belt tensioner, valve/breather cover seals, etc. This is due to the conventional rear wheel drive arrangement.
I see the Crossfire as a fun sporty option that lends itself well to the "shade tree" mechanic (and, I barely have the skills to be called a "shade tree" mechanic, yet, I do almost all the work on my car). Again, if your answer to any issue is "take it to the dealer", do not buy a Crossfire, go buy a current-production vehicle that the dealer can call the manufacturer and get help. Maintaining a Crossfire takes experience, specific knowledge, patience and insight that most dealer service department employees simply do not have. Dealer "techs" these days are the 'bottom of the heap' and are paid and treated poorly, they are not interested in your unsupported unicorn car.
