I don't know the full answer to your question without doing some research, but I think you would probably want to focus on how much Income Tax you would have to pay to the IRS.. The amount probably depends on your personal tax situation.

As far as the amount of tax you pay to the State of Texas for a car that you built, that is questionable too. Some have managed to not pay any tax, others have paid tax only on the kit and/or parts that were ordered online. It all depends on the sub-courthouse and the person at the window that you walk up to.

Good luck on winning the car!
