Lol that post is gonna be so flamed.
Flame it all you like! (Not aimed at you!) It's purely down to my belief that until you get to 100-200kgs, the weight of your car makes no difference on the road when power output is the same. Add to that that for the 80-odd kilograms I've gained a fantastic set of seats - ok, it's only a Clio but they are better than my A4s and on a par with my old man's old Merc E-class - lights which are supposed to be a shedload better (I haven't seen the standard ones on a Clio, but have seen the difference on other motors) and all the driver aids I think 80kgs is fair game.
Plus, the Cups I see are all driven by students and people on 16 grand.
