Advice on used 2007 CPO without Car Fax report

[tobago]

I just joined the site today. I came across the forum with a google search and I'm happy that I stumbled on it. Quick question for anyone who may be able to help me figure something out. I'm interested in purchasing a 2007 CPO 335i coupe but the car's VIN number does not come up on Car Fax. Is this common or potentially a scam? The dealer explained that this is an executive's former vehicle and never titled to any owner. A question that comes to mind is that on most Car Fax reports the date/port of entry to the US is available but not in this situation.

Any suggestions or questions that I should ask since Car Fax cannot tell me if this car has been in an accident or maybe a rental vehicle.

Thanks, in advance, for your help!
