Flat:
What in your opinion is the "ultimate car"--I don't think anyone is saying the XFire is the ultimate car, but for $35K it's one heck of a bargain. Because your dealer is taking long to fix your car, that does not all of a sudden make ALL Crossfires "not the ultimate car"--maybe you should go drop $150K on a Ferrari, now that is close to my ulimate car, but out of my price range.
Again, resale value should never be the sole reason for buying a car--cars depreciate that's a fact of life. Sounds like you have a bit of buyer remorse, and cannot get anyone to unload your Crossfire on, and now you are pissed. I understand, but life's tough...you signed the dotted line on the contract--no one else.
