welcome to the addiction. What you describe is as you say, nickel dime stuff. You came to the right place to get the info you need for most of these items/problems. IF your really taken with this VX and don't want to wait for another, I would spend the 100 bucks or less and have a mechanic you trust check it out, and the high cost items he might find can be bargaining points to bring the asking price down. AT 70k, your coming up (5k) on the cam timing belt change and most do the water pump at the same time. Unless your mechanically inclined, you will have to pay that and it ain't cheap.

Greetings, Earthling. We come in peace... Never mind "Paris to Dakar", the VehiCROSS looks ready for the Martian desert.
