When doing the window check, spray some water on them first. My windows go a lot slower when wet, I believe the wetness makes them bind.

Also, despite the enthusiasm on this board, the VX was not a hot seller. In order to clear the last ones of the dealer lots back in summer of 2002, Isuzu was giving huge incentives, enough for some brand new 2001s to sell for under $20K. While the orginal sticker was somewhere around $32K, a LOT of them sold for substantially less. So, don't let them know you know how cool a truck it really is, treat it like you're doing them a favor buying something that's probably been on the lot for months.

PS - in case you didn't know, a "clean" carfax record is meaningless - it may be "clean" because their data is incomplete. On the flip-side. If carfax does list some problems, chances are the problems are legit - it is unlikely that there will be false positives.
