One thing to look into. If you're married, give the vehicle to your spouse, and note the amount of the gift in a notarized letter. That then becomes the value of the vehicle for tax purposes. We live in a state that essentially has an import tax on vehicles. It's unconstitutional, but you'd have to take that to court and that would take years. We did this with our vehicles when we moved to the state. The person at the vehicle registration place was unhappy, but they had to accept it - an extra benefit.

You're not an asshole to drive around a ride you've earned.

Statists will always find some rationale for taxing more that sounds perfectly reasonable and good, when its obvious the motivation is envy.
