If it's been maintained, there shouldn't be any basic problems with the high mileage. However, some of the "peripherals" might be a problem--like windows, door locks, air conditionioning, cruise control, etc. I'm assuming the body is fairly rust free? With the high mileage, the $3600 price seems a little high. You might want to try to bargain him down. I would think that $2000-$2500 would be a more reasonable price.
