Hello,

I used autocheck (thru our website ) to look up a zhp listing and found something related to the odometer that worries me: the report says no indication of odometer rolback or tampering but the mileage #s for their reported date doesn't make sense.

Following is the table from the report:

0 Problem(s) Reported:
=============================
Mileage Date Reported
--------------------------------------
11 04/29/2004
20,000 01/22/2009 not included in rollback calculation
15,956 03/30/2009
20,700 05/27/2009
28,000 01/14/2010
30,000 10/09/2010
30,441 11/18/2010

=============================

Puzled that it goes from 11 miles to 20,000 and then drops to 15,956. Do any of the members have some plausible explanations?

When I searched on the web about "not included in rollback", I found the following on yahoo answers which could probably explain the above:

"A rollback is a vehicle that has been delivered to someone else but the sale did not go through. Generally because the buyer could not get a loan. That vehicle was returned to the dealer and it could have been driven for 2 days or 2 months. Carfax does not know the milage when the vehicle was returned." (source: http://answers.yahoo.com/question/in...9111430AAaVlwu)

Two things worry me assuming the above is correct:

(1) If mileage was not known when the car was returned, then it could be anything from 10k to 100k. Beats me how they can assign a random 20k #! Should we disregard it and assume that the 15,956 number is the accurate one?

That doesn't make sense because of my second concern -

(2) If vehicle was returned to the dealer, it is bizzare that it was just sitting there in IL from April 2004 until it reached AZ in Jan 2009 and someone kept paying for the registration/renewal (as I can see in the report).

I suspect that the vechicle was driven between 2004 and 2009 and so the current mileage on the car is understated. Would greatly appreciate the other members thoughts on this issue.

Thanks!
