I don't think I would have been able to handle the situation as you did. I would have FREAKED OUT. You must be a very patient person. I would go back tomorrow and demand my $200 back and have the entire engine bay cleaned by a specialized shop, not the dealer. I would also suggest to the dealer that the next few oil changes WILL be on the house. If they refuse, call Chrysler. Make note that this is a $35K+ Luxury sports car and it should be treated that way. I would have gone postal if this happened to my PT Cruiser, let alone my xfire.

Once again, I give you props on your ability to "Keep Cool." I can't put into words how pissed I would have been.
