I am looking to buy a used car. I checked the Kelly Blue Book value and the owner wants about 30% more. I understand thats pretty common here. I copied the VIN number from the silver plate on the car and from the original bill of sale. When I checked CARFAX and DMV.org the VIN does not come up as a valid number. Does anyone know why this might happen? The owner said the car was shipped new from the States and has been in the D.R for about 6 years.
