We've had our fully loaded XL7 for a year and a half and only had to replace the alternator. It drives great, has plenty of power and handles well. I can't wait to try out the 4WD in the snow... We are a pretty tall family of four and room is sometimes an issue but having taken it on several long distance trips, it suits our needs well.
Reliability, the seating for 7, plenty of accessory power outlets, compact size and interior/exterior fit and finish.
It would be nice if the rear seats could fold down flat. Only the backrests fold forward into the backs of the front seats which limits the ability to carry large items.
