Carfax????

Hey guys and girls I was trying to get a carfax report on a car that I was thinking of buying, and it came back saying "The CARFAX© database currently contains no records for
this vehicle. Please check back again soon, as our database is continually updated." It did say what kind of car and what year and trim, etc.... but then that messege came up. Has this happened to anyone before? Is this a really bad thing or does it have nothing to do with the car and just with carfax? As it is the dealer is kinda shady and now this, im not really sure if I should trust him, or the car!!
