Take the check and wait for it to clear.... keep checking with the bank to make sure it clears legitamately bc they do a scam where the check clears tenatively i.e. there is money in the account the bank says ok then it comes back.
once it clears and you have the money in your hand and will not be responsible for it if it comes back then send the car to the shipping company
I would be hesitant to send him my address where the car is incase they want to steal it or something....
