Hmm i never understood why people like to get cars like GTR, imrpreza sti's & top of the line Audi's remapped or upgraded power? as if their not fast enough not so bad if the choice of car isnt the fastest in the range like... + how often people use these car to its full potential?? hmm if i bought M3, lancer evo 8 etc... i be happy with performance as standard! as for fuel consumption common sense its gonna be a little worse not improved, a saying no such a thing as free lunch but this my opinion!
