I've had this car over 2 years and have racked up over 55,000 miles. I still find the xB very enjoyable to drive. The only problem I've had is with the rubber strips that run along the roof. I had 2 blow off shortly after running it through a car wash. They were both replaced under warranty. It runs like a champ and easily cruises down the highway at 80+ mph. The kids prefer it to our other cars because they have so much room in the back seat. I'm 6'1 and there is plenty of room in there. I average 27- 28 mpg and I'd classify myself as a pretty aggressive driver. I've driven conservatively a few times and have gotten 400 miles on a single tank of gas.
style, 5 speed is fun (it'll bark the tires in 3rd gear @ 55), roomy, 4 wheel disk brakes, side curtain airbags, stability control, ipod connector, rear windows roll completely down
paint seems to chip easy, need armrest for passenger seat and some more cushion for driver's
