1500 miles so far, just after two months of ownership. Was a blast to drive for the first month, but unluckily i'm having a strange issue. There's a strange whistling sound, almost like a tea-kettle, that intermittently appears while on longer drives. Nothing triggers it, it's affected by acceleration and initally relevant in the 50-60mph zone, but continues to be more relevant all the way down to 30~ish after awhile, soudning almost metallic-ey... Dropping it off at the dealer for service today, after they claimed to fix the problem once already (being the driver's side FMIC hose clamp coming loose). Hopefully something comes of this.
Regardless, i'm still enjoying the car. Anyone else on the forum would probably tell you FiST over FoST any day, but test drive them both and make the decision yourself! And then once you've made that decision, try it with recaros and without. They're definitely not for everyone, like myself. I didn't enjoy em' after a 10 minute test drive, so a 30 minute commute to work 5-6 times a week would drive me nuts. That's honestly what it comes down to. Something about the fiesta had a lot more "Spirit" than the focus to be honest, which is why i chose it.
Good luck with everything!
