The Vauxhall world parts one was the one I mentioned earlier.. £7 is cool but the £4 postage bumps it up into the realms of.. meh.. (I'm a consummate tightwad, can't help it)..
If that's the only option though, I'll probably have a bash at it.. it's a shame the trade/trade club thing has to be set up at individual dealers tbh.. there's 2 other dealers I could try, that I could be passing over the next week or so but the hassle of getting the account set up is a big ol pita.
