I just sent him a nice email asking why he is such a scumbag, I'll let you know if he responds.
Carfax is pretty good in general; it records whenever a car comes in contact w/ a govt. agency such as emission tests, title transfers, etc.. If Fla. doesn't have testing and car was one owner for a long time, it could escape detection I guess.
That car looks pretty clean, in the old days before Carfax that was known as a "clocker's delight" , custom made for odometer fraud.
