I used to work on MK2s while they were still in production, along with Porsche 924/944 and of course 911's.. quite simply, I saw the GTI as a baby Porsche, sharing many components, build quality, and image that must have been the envy of all other hot hatch makers, the bottom line was that the MK2 GTI was a "must have" piece of kit, Early 80's.. one of the most popular colours to have was white, of all things! Tornado, and Mars red's were always popular, but the real shocker is that Oak green was never a cool colour, and was usually given a wide berth by the used car world, along with Jade green (see my sig) how things change!
Panel fit on MK2's was never the best, although the pressings themselves were fine, and generally free from ripples, and production marks, though when fitted to the shell, extra wide gaps were apparent, especially on the doors, wing's and bonnet, sometimes up to 10mm wide, that's about 4mm too wide! rear bumpers were always a bit iffy as well (small bumper) viewed from the rear, the right hand side always seemed to dip, as it turned the corner, under the O/S tail lamp, though easily sorted with a shim under the right hand bumper bracket.. I really could go on, and on..

So really the golf is a bit of a phenomenon, and still look there best in standard form, maybe just lowered a touch, and some cool rims, you cant go wrong
