The seller has zero sales on E-Bay. I personally try to shy away from that. If you have a good independent mechanic check it out, Car-Fax the VIN and you like it, go for it. A 9 year old vehicle with that low of miles isn't going to be with out bugs. I am sure things have "given up the ghost" on the truck.
My guess is that the seller had the D-90 out on "Long Island" to use while the family "Summered" hence the low mileage. Good luck...Dave
