Sounds like you want to own a car. Work permit in hand, visa (I am guessing that is in order, proof of income, I would go to either a dealer or used car company. Again we have no idea what city you are in ?😳
My question to the OP. Have you been to Thailand before ? I am with the majority here. Start fresh here. If you have you must have seen you can buy all the items you want to bring. You are creating more issues and problems than it's worth. smh...
