My friend bought a 200K+ optioned Cayenne Turbo and she made a mistake. It has about 4000 miles on it. She wants to sell it and I don't even know how to sell something that is so optioned. What is the best way to go about selling it? I am sure she will take a hefty hit on this. Use an auto broker? Sell it privately and list it on websites? If so which ones are best?
