[Josh1994]

Hi all, just need to what is the gti 6 like on fuel and dose it have many errors and on a convertable can i change the front and rear bumpers to a phase 3? I am just waiting for a quote for my hdi insurance and if it is cheap then i will get another quote for a gti 6 if that is cheap aswell then i will go and make a person a offer as he only lives round the corner from me, also what is the convertable like? Are both cars smooth to drive? And what is heavier the gti6 or the convertable?
Thanks..
