Boot badge appears to be fixed with a 10mm bolt in addition to pins and glue. (See attached pic.) which I suppose accounts for the difference in price of the two badges although they appear to be of identical size.
I've just changed my grille badge £17.70 inc. VAT and post Bought from AO classifieds (came from AutoLosso), with help of 156-2.5-V6 excellent photo guide. Only problem I had was that unlike the rest of you experienced guys on here I expect, I dropped one of the 10mm bolts into that space behind the N/S headlight that is full of cables, connectors, little shelves to catch things, but not my bolt! I suppose it will fall out sometime! Anyway next time (if there ever is a next time)I'll put a dust sheet over the engine before starting.
So I started looking at the boot badge and have a quote of £27.80 inc. VAT and post from EB Spares. Anyone seen any other price please?
