I just got my Fiesta ST and I am very pleased with it. The handling is excellent, all controls feel precise, and it feels surprisingly solid and well-made. It's pretty powerful, though slower than my stock NSX, which i expected. One tech feature I really like is the voice recognition, especially for music. I put my music on a USB stick, leave it plugged in, and just say play (name a song) and it plays.
I wondered if the ride would be too hard, and it's not so far, not as hard as my NSX on 17/18's. I think they nailed the ride/handling balance well, as well or better than the E90 M3 that was my previous DD.
I read that this car is the cheapest one to have Recaros (optional), and they are necessary with the car's level of agility.
The motors are used virtually stock in Formula Ford, which indicates they're tough. This is a serious car for an enthusiast, but very cheap to run, and seems ideal for an NSX'ers DD.
