While looking at used Chrysler Magnums in Canada I have noticed that Carfax records show vehicle registration dates in 2007 while Chrysler "In Service" dates are stated as 2008 with over 13 months difference. This has happened twice on vehicles coming off lease agreements. Although it seems to be a benefit in receiving additional warranty coverage (over a years worth), it leads a buyer to believe the vehicle was on the road for a shorter period of time. Is there an explanation for this? Dealers tell me the Carfax records may be incorrect which I doubt since it has happened twice.
