I used to own a 197cup, Renault offer them for a great price, huge downfall of the car is that you are lucky to return 27mpg, drive it with authority you will see 16-17mpg. Really not good.
They are lovely cars inside and out, was it the fuel consumtpion that made you get rid?
I think this will have to be put to the test somehow, im dying to know. Ive never driven a abarth but i know that my GP is way way way faster than my mates clio 182. but i dont know how that compares to the abarth. (i might even say that so much faster that on B roads the time he would make up on the corners wouldnt be enought to catch up)
I'm sorry but a remapped GPS can't possibly be way way faster than a clio 182. Not a chance! Mine was level with a clio 197 and was running more than yours.
