Considering a ST?
According to Motor Authority:
One other thing potential buyers should consider carefully is whether they want the deeply bolstered Recaro sport seats or not. We appreciated their firm comfort and good support (no bracing required in the passenger seat). But they'll prove simply too deep and too narrow for many American-size drivers, so if you can, sit in them. The base ST gets essentially the same seat that's in upper-trim U.S. Focus SE models, so wider drivers should stick to that.
Months ago I sat in a ST with the leather Recaros. I'm 6'0" / 165 lbs and the driver's seat was *snug*. Motor Authority is not exaggerating in the slightest about the bolsters being deep and narrow. If you (or your passenger) are even slightly wide, you should either try before you buy or go for the base model.
