Hope this isn't against forum rules but anyway, [url="http://www.ebay.co.uk/itm/Vintage-1984-ESP-Japan-Horizon-Bass-P-Style-Fender-Tweed-Case-/301336252522?pt=UK_Musical_Instruments_Guitars_CV&hash=item46290a506a"]http://www.ebay.co.uk/itm/Vintage-1984-ESP-Japan-Horizon-Bass-P-Style-Fender-Tweed-Case-/301336252522?pt=UK_Musical_Instruments_Guitars_CV&hash=item46290a506a[/url] is a bass I sold for £10 less than I paid for it (around 300/350 I think) - as an experienced bass player, I can honestly say it is not worth this sort of money!! Looks like profiteering to me, or I didnt know what I had but, pricewise, it seems to match 2nd hand warwicks and stingrays, and it certainly does not match those.
I suggest a haggle. You've got to.
