Sale of car to family member in a different state

[BuckeyeFinance]

My dad would like to purchase my car. He lives in Texas and I live in Ohio where the car is registered and titled.

Does he owe sales tax on the purchase? How do we determine which sales tax rate to use?

How do I calculate what taxes, if any, I will owe on the sale?

Any suggestions to save money?

Sell it to him for $1.

In a totally unrelated matter, he can gift such a loving child up to $13k tax free in any one year (or maybe more, the rules change as the years go by)
