Personally, i do love S1's.........but.........you drive a well looked after RS and a well looked after XR3i and i would say the N/A engine is a lot nicer to drive, and you don't suffer the dreaded wheel spin the RS's are prone to. This was probably a big contributing factor, aswell as the difference in the price tickets.........

And additional to that the 0-60 between the 2 is very minimal
