I have sold 2 Crossfires and a Porsche on Ebay. Have bought 3 Crossfires and a Porsche on Ebay. Maybe I am lucky, but have not had any problems. Limit buyers to US and must have at least 5 positive reviews.

Demand deposit within 12 or 24 hours.

Give a good description of car, including any defects and service history. Lots of pics.

Good luck.
