Are there any websites that check the history of a vehicle for free? Most I've been to give me just the vehicle's primary statistics but want $$$ for a full report.
If no one subscribes to carfax on this forum, perhaps ask on a forum specific to the car in question or just other car forums.
When you ask, in the subject line put 'Carfax Please'. In the message area post your vin number. Then someone can answer with the first reply if they know.
Your state motor vehicle department may be able to give limited info when they are presented with the VIN..
Indeed, at times they can be most helpful...
If a boy owns and races/abuses the automobile, then has the engine cheaply rebuilt, is CarFax going to learn of this and how ???
An accident, yes, most go thru the state system - police reports, etc, but not shade tree maintenance..
Factory recalls, yes, I would guess Carfax would learn of these things.
Most car makes have their fan clubs/tech sites. Saab has an excellent one - all the weaknesses are public and known..
