2007 Mustang GT Premium auto 37K-mile 12-second car

2007 Ford Mustang GT Premium Description

2007 Mustang GT Premium AT, 12-second, 1-owner car
Bought new with dealer-installed Drag Pack (cold-air intake, shorty headers, 3.73 gears), X-pipe and axle-back exhaust. Also had the dealer swap the 18" wheels with 2006 Mustang 17" 5-spoke mags.
I then added a Precision Industries Stallion 3,000 rpm torque converter, Spydershaft 1-piece aluminum driveshaft, cmcv deletes and underdrive pulleys, all professionally installed. 12.89 ET @ 103 mph after 2-hour drive to the track.
I've since taken the car to JDM Engineering in New Jersey for a custom tune that feels much stronger than the previous tune but has not been back to the track. SCT tuner from JDM and all of the stock removed parts are included.
Car has never been driven in winter, always garaged and got better than stock gas mileage. Still has full factory stainless exhaust and passes CT emissions. On its second set of Pirelli P235/55 ZR17 tires, which have very few miles. Interior is immaculate; exterior has only the minor chips expected with 37,000 miles. In Newtown, CT.
