I can sum the answer up real easy:
YES, THE RECARO SEATS ARE WORTH EVERY PENNY!!!!
Due to vandalism, I just dropped my car off at the body shop. Enterprise gave me a new VW Jetta for a rental. It has leather, or leatherette seats. VW stock seats are way better than any standard Ford seats. Especially Fiesta seats. Just getting in the car, and I missed my Recaro seat instantly! In only a few weeks of having the ST with Recaros, I am SPOILED! I don't think I will ever be able to sit in any other seat again.
So anyone asking if they are worth it - are you truly wondering if they will fit you? Or are you trying to justify to yourself because you don't want to pay the extra cost? It doesn't really add that much extra cash to the monthly. And you'll be kicking yourself later for not getting them! They ARE so worth it. They are part of the reason I got the ST. All my other cars, I either just missed the models that had them (MKIV R32 had, the MKV did not), or I spent $$$$ to install a Cobra Missano R seat (my WRX, then went into my STi, but too wide for my R32, argh!). And going aftermarket is a major PITA, cause nothing ever fits right.
And for the record, I am 58, am near 6' tall, and can weigh between 235-250lbs. So if I can enjoy them, what's your excuse?
