I just paid $27K for almost the same car, 09S. (Early March) No NAV, Seal Grey, Sports Chrono and it has a small spot on the rear bumper. It had 25K on the ODO. It has +/-$9k worth of upgrades. Intake/ECU/exhaust and Bilsteins BSS'9s with newish Pirelli's P-Zeros. The seller was asking $27,5 for it in Indian Wells, CA.
I forgot to add this car has the PDK trans.
