CarFax crap and passenger side airbag cover

[icedude]

I ran a CarFax on a one owner Boxster that I'm purchasing and it came back as being owned twice, yet the dealership where he bought it and has had it serviced the entire time confirmed he is the original owner and has had it maintained there since purchased in 2001. Ray Catena Porsche in Edison, NJ. The VIN number is right so how can that be? I know CarFax can be crap but how can they get that wrong or is something going on here?

Also, car checked out fine but I noticed the passenger side airbag dash cover loose at the bottom and slightly sticking out (please see attached photo). Has anyone else had this problem or could this be an indication that it was once deployed (ie. an accident?)

Should I question the owner about both or will I risk him telling me to pound sand? Nice guy, seems straight up.

Thanks,
