Re: how many miles on your xfire? major problems?
41K here. I've owned it since 34K, and so far the only problem was a leaky transmission. Was a quick fix done when I had it in for the scheduled maintenance last month.
Everyone complains too much about ride comfort. Either you all are driving down dirt backroads, or you've been spoiled by road-couches. I drive on old bumpy roads ~30 miles daily. Really I don't see whats so damn bad about it. Sure it's not as soft as an SUV or something, but it's not THAT bad.
