MTO only follows book for a certain year range. I'm hoping that my 02 stang falls outside of that range when I register in the spring, as I legitimately bought it dirt cheap because the p.o. spun it in the rain and it instantly became a 'project'. If they try to tax me on market value of a convertible gt, it will probably cost more than what I paid for the car.
That's where a legitimate appraisal last fall (which costs less than a couple hundred $) could have helped you out.
