I just purchased a 2004 x3 in January with 90,000 miles. I had the dealer replace a master window switch, thermostat, a leaky oil filter gasket, the cooling system reservoir and change the transfer case lube. All in all, I love this car. Look for a late 2004 or later as the early ones aren't set up for cell phone or satellite radio. Mine is one of the first ones so no fm input to the radio either.
