We have had our 1995 Xplorer 230 on a Dodge 3500 for about 10 years. Now has 67,000 miles on her. Knock on wood with little to no problems. None age related just normal tires and brakes. Did have radiator replaced which is only thing I might consider age related. Only thing that has been constant problem is Onan 2800 gasoline generator. I own several older vehicles. One is a 2004 Dodge Durango with 284,095 miles on it. I have replaced the radiator and recently 1 of the 2 water pumps. Other than that and normal tires and brakes replaced nothing else. I would never let mileage or age stop me from buying a vehicle.
