I have a 2010 Tesla Roadster with 11,500 miles in Mint Condition that I would like to sell. Can anyone recommend the best way to sell this car and how to establish market value? Tesla said it was very difficult to assign valuation since it is a collector's car. I looked online and people are pricing them anywhere from $90k to 1.5 million! Any advice that anyone can give me would be greatly appreciated. Thanks!
