Sturdy vehicle, my biggest complaint is the ac.
Starter went 2x, heat doesn't work in back, heat went in the front this winter (on again off again), trim around sunroof falling apart, front seat makes odd noises when moving forward/back - I swear it was new! I have 54k miles and $15,500 left to pay. Any takers?
