Best advice I can give, Let the Prospective Buyer make You an Offer and see how serious He is. You can always decline after that and make a counter offer so You won't look like you're trying too gouge him too badly. I have too say, $49,500 is way too high for an O4, I bought Mine from a Dealership, only had 21K on it and everything works like a Champ. I paid less than Half that cost you are looking at. Just a Thought...Let Him do the first Move...Might pay off more than You know?
