Thanks for the info. I'm going to go look at a 2012 CPO this weekend. Though it sounds like it may be worth it to wait a bit longer to look at a 2013.
As the current owner of 2014 PP SHO and previously having owned a 2011 PP SHO, I would definitely hold out for the 2013. I loved my 2011, but the brakes were horrific (I bought the car new, so they weren't worn). They're good for one hard braking event, then braking is severely diminished until they cool. I went so far as to install a 2013+ master cylinder and power brake booster, which helped, but the brakes were still disappointing. While I had the 2011, I purchased a 2013 Ecoboost Flex as a second car. Since it shares it's powertrain/platform with the Taurus, it had many of the same updates the Taurus got that year, including the brakes. I was shocked how much better the 2013 brakes were. Within 3 months, I got rid of my low mileage (12K) 2011 SHO and replaced it with a new 2014.
The brakes are so much better it's nothing short of amazing. No fade after repeated hard stops and a much firmer pedal. In addition to the brakes, the 2013+ model's steering rack is hard mounted and torque vectoring is included. The 2014 offers noticeably better chassis feedback and is more responsive, making the car more enjoyable to drive.
As others have noted, the 2010-2012 center stack (non-touch-screen radio/climate controls) are better, but interior materials have been upgraded in the 2013+ cars. In addition, the sharpness of the LCD displays are much better on the newer cars.
