how well does this care do with high mileage? (166,000)

The cost of ownership does increase with higher mileage. I have customers who love them and I have customer who hate them. It all depends on the care the previous owner gave it and the state it is in. I would recommend having a 3rd party shop give it a great inspection and give you his opinion on it. And always remember you are taking a risk no shop has the crystal ball to tell you the future of your car. They can only give you a opinion on what they can see.
