I have 4,200 miles so far on mine and I love it! My MFT is working great, once I cleaned up my music files. If you're technophobic I'd recommend not getting MFT, otherwise its a must have!
The Powershift is pretty amazing when you think about it. Its a manual transmission inside, but drives like an automatic. At a stop light it will creep forward like an automatic. I like how quick the shifts are. In normal mode it does shift to a higher gear more quickly than I'd like, but thats the trade off for better gas mileage, and the mileage has been awesome.
All of the materials inside are high quality and feel good to the touch. All of the controls are well laid out and easy to use. Its also very quiet inside. Overall it feels like a higher end vehicle than you'd expect from a Focus.
The quality of mine has been very good. I know they added robots at the factory to improve the fit of the doors, but I don't when that started and if mine was built after the robots were installed or not.
