Bobs you bring up an interesting point. If a dealership sells Crossfire's they have to have at least one certified Crossfire rep on staff who can work on them. At the dealership I bought mine from I know the service manager, he's also a client of mine. We have had a few interesting discussions about this and to be honest I'm not sure that certification is all its cracked up to be.
When I asked about "their" Crossfire specialist I got a chuckle. We have a guy who has some expertise. So far the two issues I've had with my car they have fixed but their XFire specialist failed to reset the oil change reminder,I ended up doing it to save another trip back, They didn't have a clue about what was going on with the headlight haze. They just keep replacing them. When I told the Service mgr about the 3m plastic cleaner he was very appreciative. Like I said they did a good job with my fan recall and lid lock, KOW that's all the problems so far. i guess my point in all this is don't be so sure that just because someone is certified they know how to work on the car. There are people on this board that seem to know far more about the cars than the dealer mechanics and I don't mean to slight the few that post here who DO know what they are doing and are a great help to us. I'm guessing the major issue seems to be with the transmissions. Be sure you test drive the car. As you would with a used car, look for leaks under the car. Some of these cars have been sitting on lots for a while. The headlight haze is another issue that comes up a lot. If its truly moisture than the fix is replacement, if its a haze on the plastic it can be easily cleaned with a plastic cleaner. My best advise is a thorough test drive then look under the car and pop the hood and look for leaks. You might want to check you local Better Business Bureau too. See how that particular dealer stacks up with complaints. Hope this helps and I hope you find one you like.
