We just purchased two 2013's - one SE with 201A and one without. No appreciable difference with brakes - rear discs vs. drums. However, at higher speeds or with repeated stops, there could be a difference. Option 201A is worth the money - not only for rear disc brakes but for many additional features: leather seats, steering wheel and shifter boot, power driver's seat, ambient lighting, Sirius radio, brighter trim inside, perimiter alarm, fog lights, rear wing and 17 inch wheels/tires. 201A is $ 2,640 in US dollars. By the way, the SE without it works fine and has nice features for the price:16 inch alloys with decent tire size, SYNC with MyFord (works fine), all electrics, cruise and more. Both cars are impressive in design, engineering and driving dynamics. And they are very attractive inside and out.
