That wagon is beautiful! I don't know you at all, but considering what site you are asking the question on, it would seem like having a finished car wouldn't be that fun. If it were me, I'd be hesitant to do anything to a car that looks that good.
But again, you may be at a stage where you don't have the time, or money, or ? to tinker with a ride and are just looking to enjoy the cruise. Seeing what you CAN do, I'd imagine the best scenario is trading for an unfinished wagon and a bit of cash or whatever- then go nuts!
