Tom & Ray aka Click n Clack would give you two answers.
One would echo Martin's comments about problems you may have with slightly used older cars and the concern on lack of saftey features.....
on the other hand. Look at the adventure you could have driving it back yourself with your son riding shot gun. I mean shotgun, you may need it to fend of the wolves when you breakdown in the middle of nowhere and the Mounties haven't found you yet.
But seriously, the car should have some good miles left in it, and someone can benefit by having it. If has had regular exercise the seals should OK, if not, you will know everywhere you have parked.
Good luck and make someone happy.
