Hmmm, everybody i know says the same as i do(easy to say i know )but my experience with both cars(have had several of both)is that the xr3i mk. is heavy compared to the S2. I know a guy who had an S2(before he smashed it completly)and it drove about as you say 225km/h, he then gor hold of an xr3i mk.4 box and then it drove 235 km/h before the rev limiter stoppet the accelaration, so i dont get it that it should be the same, why have different ratios if the outcom is the same
