2007 audi q7 - $4,500 (Sacramento)

Hello, I just purchased a new car and decided to sell my 2008 Audi Q7. I’ve owned this vehicle for a while, and it served me very well until I bought me a gas saver in January, so I no longer need this one. The AC and heater, I believe, need to be recharged. No check engine lights and no mechanical issues. However, I recently noticed that it’s leaking oil, but it’s also been sitting since purchasing my current car, which was 7 months ago. I don’t see where it can be coming from; my dad said it can be the oil pan gasket or the oil filter. I’ve always kept the maintenance up on it, so it shouldn’t be very much wrong with it. It’s a six-cylinder and, I don’t know much about cars. Come check it out and take it on a test drive for 4500 or best offer pink slip in hand. Rims were taken off and replaced with tires!!
