I don't see where it has the ODBII connector and interface nor any mention of code reading or reset ability. Sounds like a lot of workshop CD info which for the VX is downloadable for free on my site - it has flow charts for diagnosing and resolving problems.

I hope I'm wrong but you might want to ask the seller some more questions. Unless you can get a good deal on a Dell...

Things that sound too good to be true usually are just that.
