65,000 with all the books and records...
I would go for it! I will try to lower the price but, realistically, you are NOT going to find too many cars in that condition for less price. I would still have an inspection for peace of mind. YOu can do a search in the internet with bluebook.com, autotrader.com but the prices there are averages only. The condition and records of the car will alter the price tremendously. This is specially true for MB's.
