This is more of a warning for buyers than a guide.

 Chrome Signum fog light surrounds seem to be selling on Ebay for £40+, which is well overpriced as they are only £27 from a Vauxhall main dealer.
 If you are watching some on Ebay then do yourself a favour and pop into you local Vauxhall parts dept and and them for a price to save you paying over the odds + the postage.

 The reason for this warning is that Ebay is supposed to be for bidders to get barains in true auction style, not for sellers to buy from the main dealer and fleece the public for their own profit.
