i recently bought a camaro by making payments to the guy. we wrote up a bill of sale that agreed to split the amount into 4 equal payments, with me taking possession of the vehicle AFTER IT WAS PAID FOR. no problems whatsoever. i mean, don't get me wrong the guy is a friend of mine and the car was paid off in a week and a half lol... but regardless, if he wants to make payments, fine, just don't let him have the car.
