Ok I have been a member of the Seat cupra site for many years and I have owned both a cupra and cupra R (old shape).
If you are looking at the new shape Leon then surely you are looking to upsize your car to this kind of car size/weight.
If what I have gathered from my time over at meganesport is correct, then really, less is more. If you are looking at a Leon(which I like incedently) then surely you are moving away from the smaller fast handling hatches into something more comfortable?
