Actually CarFax is good for a little more that this.  It gives odometer
info, i.e. rollbacks. and also lets you see the car's history.  I was
looking to buy a Eurovan in South Texas, low-miles and "rust free here in
South Texas".  Well after punching the VIN in at Carfax I found out the car
spent the first 5 winters of it's life in Minnesota.  And the reported
mileage was a little suspicious too.  5000 miles in 2 years!  I ran, not
walked away from this van.  If you are looking to buy a car don't pay $15
for a One-time report, spend $20 for their unlimited searches for 60 days.
CarFax was invaluable to me as I found my EV MV on the internet for an
Awesome deal.  It is a tool you can use to limit your chances of being
scammed.
