have 87K miles on my wife's '05 Escape. It is the V6 and AWD. It is a good little runner. The only problem we have had with it is the fuel pump died at about 75k, but research hasn't shown that it is a common problem so I'm just guessing it was a fluke deal.
Pretty quiet inside, decent room (I'm 6'2" and fit fine, the back seat is slightly cramped though). It handles well for what it is but is a little squirrelly at higher speeds because of the short wheelbase. Motor make the power up high; starts pullin hard around 4000rpm. Second gear is a jump in the ratio and it falls out of the powerband... Normal driving it has plenty of power. Offroad not so much. My wife for some damn reason loves to take her's to the beach, buried it once. It doesn't have very much suspension travel and no traction control devices. Works well in snow, it doesn't slide unless you make it slide, some wide-open-throttle turns makes for some good 'rally' turns.
Fuel economy: Unless your mean to it, you will get more than 20. Highway is easy to hit 23-27mpg, city 20-22.
The spark plugs on the V6 are stupid to change. The front 3 are a cake walk. The rear 3 require you to remove the plastic intake manifold! If you feel inclined go and buy the manifold gaskets and set some time aside. If your feeling a little bit uneasy, take it somewhere, it is easy to screw up and drop something down the port.
The back seats fold down ALMOST flat. Speakin of back seats. The stupid headrests are right in the way of the mirror to look out the back window. We took them out (super easy to do) since hardly anybody rides back there anyway.
Oil changes are easier than on my ever so popular 350ci Chevy motor ('97 GMC). The oil filter on the V6 is at the front of the motor and my only complaint is it is directly above the exhaust pipe for that cylinder bank, so oil gets on it.
That's how I feel about the Escape. I have heard good things from others about theirs, am happy with ours, and wish you the same experience. Your price sounds about right for the mileage.
