karmann ones in good condidtoin are poop!
as for the rear badges, they go for silly money nice ones, but i bought the Volkswagen opne for 50p at Gti spring fest, they guy had loads, altho some were missing clips, but at 50p i shoulda got the other one, as the ones on my cab are black.
gunna keep out for some more! good luck in finding some! another option is to paint yours, but its never the same!
