yeah, non recaro's are alot cheaper.
presonally i wouldnt put the 197 recaros in my car, as they wear very quickly, and as an aftermarket mod you couldnt get it sorted under warranty.
having said that Recaro CS's are probably better trimmed than renault ones, so may not wear, but then you are buying two brand new, reclining recaros, and thats never going to be cheap
