my gti is in rough condition, there is a blemish on nearly every panel but its not rusting out really bad yet only in the area of the gas cap and under the front wind screen. im thinking about doing a restoration and wa wondering about body work, how much do you think it would be to get it done and is it just cheaper to get new panels and hatch all together? and how do u change the rear side panels as it seems to be one piece?
