Where can I find Used Car Sales Data?

I currently have a vendor that provides this information for many states (in the USA), but does anyone know where I can get the data for the other states (New York, Alabama, Georgia, Etc.)? Individual DMVs/BMVs probably wouldn’t work.

The data I receive monthly is the Title registrations for a given area with the following data:
– VIN
– Year, Make, Model
– Selling Dealer
– Month Registered
– City, Zip Code, County of Purchaser
– Lienholder (if any)
– Odometer

Hopefully there is a vendor that resells this information in the states which are not currently covered by the vendor I am currently using.
