I wrote a system years ago that did car property tax assessments. The system I wrote used an annual tape from NADA -
http://www.nada.com/ then matched certain sections in the VIN and cross reference them with the cars registered year. If they didn't match then it kicked out the car to an error report for follow up. After that it did a straight multiplier of the NADA value to get the tax amount.
