I have had mine for 2.5 years, 32k miles from new all great its running the Code:Red 295 spec, you can not fault the car it does everything perfectly. Now they are cheap to buy they are really worth that test drive. You will get hooked on the sound on the engine, once you remap them they get even better.
The market is shit for them at the moment so go grab a bargin!!!
I have owned 2 Focus RS's and as a day to day car the ST its miles better, if you arent doing massive miles and a few track days then look at the RS (or better yet wait for the new one to bring down prices.)
