Just spotted a thread about bumpers. They may be available from Euro Car Parts. They are on the website but listed as out of stock. I ordered a pair, just to see what happened, and lo and behold they arrived a week or two later. Around £46 for the pair inc delivery when I ordered. Price fluctuates depending in which particular sale is on at the time!
