Your last post is difficult if not impossible to respond to without seeing the car. Have you taken it for an inspection by a professional? I think your hesitation is very wise. Used car lots typically have cars that were not good enough to go on the dealers lot that took it in trade.
The mileage would not bother me if the car were solid and well cared for.
Keeping in mind that this is a premium 201 car as far as how it is equipped goes. It might be worth having inspected by a professional, if it looks good to the pro, see if you can get it for a fire sale price. If you can't, honor your instincts and let him keep it.
Sorry I can't help. This is a personal decision on your part.
Best of luck,
