I don't think the track cars had plates on them when I went. I wouldn't be surprised if they were never registered at all since they never left factory hands till that had finished ravaging them.

As for CarFax, it won't tell you anything about that. CarFax is actually a false sense of security. They aren't all that reliable to tell the truth. That guarantee they have is BS. Nobody ever signs up for it, so they hardly even get a claim on it. Even though alot of the cars they show as clean with no problems have been wrecked and stolen or whatever. The only thing they are 100% on is wrecks where a police report was issued and title problems. If the car was in a signal vehicle accident or it was a minor accident and there was no police report, it WILL NOT show up. I see cars all the time that have good carfaxs that have OBVIOUS paint and bodywork. Its commonly believed that a carfax problem is reported if the car has an insurance claim or has been repaired by a dealer. That isn't the case. A few Car brands and dealers report to them, but not many. Hell, they don't even show recall notices most of the time. Most carfaxs will show that "no recall information is provided by this manufacturer" You really think Ford wants a consumer to know that 2002 Ford focus they are looking at for little Suzy has had 11 recalls? I think not. That would make them look bad to the consumer. Carfax.com advertises for car companies, you think that would continue if they published information that showed their vehicles is a poor light? Car fax is snake oil... The same can be said for Consumer Reports, Motor Trend, Car & Driver etc. Whoever pays them the most advertising money gets the best marks...

If you want to be sure about your purchase, have a certified independent mechanic closely inspect the car. It cost more than a carfax, but its a better bet. Carfax has its uses, especially for title issues, but the history report is about 50% bogus at best...
