The megane is a far more enthusiast type car (LSD, Brembos etc as standard) the 265 with a few most is very very fast round the track and B roads with more than enough power to satisfy most people requirements.
The stage 2 cupra would have it in the straight line but the megane is much better out the box and has poor resale values, i owned a 225 previous and allthought it had its issues, was a great car.
The 265's ride isnt half as bad as people make out, some internal parts are forged to take much more power and ive seen a few with 330bhp which is a great mix of power and capability.
Much more reliable than the older models aswell and are much nicer inside, id have one if it wasnt for the fact that the resale values aint great and my insurance is silly, best hot mid sized car there is, and im a big SEAT fan.
Theres a reason why it holds the record round the ring for a FWD car.
