Looking to sell (or trade for a turboS cab or McLaren cab) my aqua blue / black 2011 turboS with 13.5K miles. Car is in great shape other than a couple stone chips.

Anybody with any recent sale price or auction data they would be willing to share? Going to talk to the dealer about trading it in on a new S550 for the wife and would like to know what's a reasonable offer.

Thanks
Patrick
