I've a 13 plate, 6300, luggage, scottoiler etc, etc, and offered £3500 against a brand new R1200GS, bloke showed me the 'book' price at £3250. I paid £4850 off a dealer last August, in Blackpool, so probably about right, unfortunately. Private sale is definitely the way to go. I reckon I'd get £4300 here in NI, used prices are a bit stronger
