So we bought that 2015 X1 I mentioned we were going to look at. It's really a gorgeous vehicle - dark gray with black interior, with 55K miles. Drives really nice, very solid. Carfax was good as well. Oh and the tires look almost new. We drove it home but wont be driving it until it gets back from an oil change and transmission flush tomorrow - something I do immediately with any new car we get. In any case I appreciate everyone's input, it certainly helped us a lot.
I'm sure I'll have other questions as we get to know the car.
