My brother had a 2005 Ford Escape for about 56,000 miles. The only problem he had with it is that the cruise control switch on the steering wheel went bad. He had to get rid of it due to circumstances beyond his control. (Well, actually, they were well within his control, but he denies that. But that's another subject..).
He sold it to CarMax. The sum total of what I had to do to get it ready for CarMax is to top off the fluids (coolant, power steering, and battery water--not that I think Carmax would've even noticed or cared) and I changed the transmission fluid because it has a drainplug and I had some leftover Mercon to get rid of.
CarMax appraised it in excellent condition and my brother got more than enough to pay off the loan and give that [censored] he let screw him over some money. But, as I said, that's for another subject....
