I'm not capable of doing that but here's a suggestion. There are two Carmax lots in the Las Vegas area. They will evaluate and make an offer to buy late model, clean cars. The offer is in writing and good for 7 days or 300 miles. He could take it to them, if they make an offer, it will at least tell you that the car has no major problems that can be detected by a normal pre-purchase inspection. Their written offer will also give you a low end value for the car (Carfax tends to offer auction level price). There is no cost or obligation to take it in.
The other option would be to have a VW dealer do an inspection, but that wouldn't be free. I would recommend Findlay VW in Henderson, NV at the Auto Mall for that.
