its ebay afterall mate
i dont bother with auctions that the bidding is private
you could get an electric aerial almost exact from a stereo place for about £30
the fuel pump cradle is quite a good bargain at £50 tbh
ive seen these go for a lot more and there the 14 yrs old ones
also its all down to how much people are willing to pay
last few items i sold were a set of rear xr4x4 calipers, bear in mind i usually scrap these as they arnt worth sod all they went for £92
and a propshaft doughnut i usally sell at 40-50 when i have a few spare sold for £90
but as i said if someone wants it bad they will pay the price
