While my car is at 136K Miles (06 330xi), since I've gotten it, I've done a lot of preventative maintenance on it, and it definitely helps that the previous owner did everything else to it before it needed it. I attribute the care the car received to the reason it runs so smooth to this day. At that mileage (200K) I'd recommend being very wary...regardless of how well cleaned it was and all that, you can bet your ass that things will need changing, left and right at that mileage, on any car really. Just something to think about, but you said you won't keep it for very long anyway, so it shouldn't be an issue.
$14k for a 200K+ mileage car is a little unreal. I wouldn't be that optimistic.
