"Starting today (Jan 15th 2006), AutoTrader.com will highlight every Carfax One Owner vehicle listed by participating dealers. When used car shoppers search
inventory listed on AutoTrader.com, they can immediately identify cars with only one previous owner."
I think this is actually a good idea and something I was going to have
implemented on our new dealer website, but using the Blue 1 Owner logo you see on
the actual online CarFax.
I forget where but I think I recall reading that 1 Owner vehicles can bring
an average of $400-$600 more front end gross.
