How does a change of state residence affect a automobile lemon law claim?

I purchased a car in FL. lived and used it there (with great difficulty and trouble) for most of a year. I then recently moved (last week) to TX and the problems continue to plague me. Might anyone know if I should pursue a lemon claim in FL or TX?

Is the car new or used?

If it's used, there is no Lemon Law.

purchase the law in the state the car is registered so you can make your claim official.
