Carfax is your friend!
I just signed up for the 30-day plan, and WOW there's a wealth of information out there.
I almost bought a VX out in Cape Girardeau, MO...until I saw that it had been in a front-end accident serious enough for an "airbag deployment" to be registered.
Most other VXs I've checked out have been clean, though.
But I really encourage you to invest the $25 at Carfax.com...or at least email ME the VIN so I can check out a potential VX for you.
