Default rollback calculation

Looking at another vette. I pulled an autocheck It said there is no faults with a score of 94 out of 94..but what is the rollback calculation all about? maybe they were lemons and rebuilt? possible gm buy backs?

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.

Carfax has been known to be incorrect on this type of thing before....

buy the only way I know how to roll back a odometer is to swap the guage cluster. This can only be done by a dealer since you have to re-marry the new cluster with the car's PCM. The dealer is them suppose to move the actual odometer readings form the old cluster to the new one. There are time when that is not possible - but very rare.

Thanks,Matt

A rollback is when the odometer has been "rolled back" to a lower number. (not easily possible on a C5). This is autocheck, not carfax.
"Not included" was because it is a small number within a close date, meaning that is a reporting error, either by typo of the mileage or the date. No one is going to roll back mileage 30 miles, even if possible. Autocheck merely did not include this as a reported rollback because a sensible person would not do so either. Had it been a large number, or a lower number after a longer period of time, it would have been reported as a possible rollback.

No expert here but this is the most reasonable explanation I've seen. Its easy to imagine the seller of this car reporting mileage, then driving the car home and back one more time before the sale actually went through. The new buyer would get actual mileage reported when they purchased it. Hence a 30 or so mile difference. No reason to report a rollback warning, just clerical differences.
