i dont like the bumper either, nor the tailgate. I'd like a standard clipper one but there impossible to find on there own. I bought the car already sprayed, it was a state when i got it, needs a lot more doing though.
So far i've put the wheels on, done the steering rack, strut tops, seats and got the doors and boot to open (no handles anywhere!). The front bumper's cracked, so if i can get a clipper one i'll fit that. Paint's some silly amount though and chances are it wont match.
I've put mk2 gti seats (front and rear) in it, am going to attempt the door cards at the weekend, want to use the mk2's material so it matches the seats, should be fun!
