I duno tho, makes sure you have pics and have a look at it...
My GTI was a Cat D, needed: Wing, Electronic headlight, grill, front gti bumper +fogs, indicator, bonnet, slam panel + spraying etc
If your doing it yourself, shouldnt be too bad on the money front
You only need an MOT to put it back on the road, where as Cat C etc reqiure a V.I.C test
