Honestly in the current climate and a market fairly flooded with SV's do you think he could £3k with 27k+ miles on the clock. You can buy a new one for £1000 more.
3 Weeks ago I got offered £3200 for my 56 plate with 3400 on the clock in pretty much as new condition with FDSH. I wouldnt have thought i would get much more privately
Edit: If anyone want a fully faired SV650S sport £3500

(Although even at £3200k I have no doubt i would still have it in a few months time.
