This is an update on my previous review titled. 140K Upright Go-Kart Written by George on 06/14/2008. This lil'car with lots of interior room is still super reliable. I have replaced normal wear items like tires, power steering/water pump belt and front brake pads. I change the oil and oil filter every 5k, air filter every 6mo. and transmission gear oil every year. I suck out the power steering and brake fluid with a turkey baster and refill every year. The xB is pretty good in the snow with all season tires, however, it's super stable and near impossible to get stuck with snow tires.
