Too many unknown miles.
If you knew the previous owner...then maybe, but personally I would never buy a used car with that many miles...regardless of who the previous owner was.
The car is out of warranty and you have no idea how it was driven or maintained. Repair cost for these cars are insane... From what I took away...you're concerned about price which is understandable...but the cost of ownership is another important factor that many overlook.
What good is saving $3,000 on the price of a car, when you'll have to shell that out during the first repair?
I'd keep looking...
