I have a 2008 Prius Package #2; 26000 miles to sell. It's in good condition, serviced at a Toyota dealership. By looking at autotrader, the price is around $20,000, so I was thinking to sell mine around that price. What do you think a fair price (ballpark) would be? I will put an ad on craigslist, and I was wondering if I should also put it on autotrader ($70 fee). Do you think I can post my ad in the "Private Sales" section of the priuschat forum? Thanks
