The saga continues!
I thought I'd try wewantyourmotorbike.com, just to see what they'd offer. Turns out they don't, milage is too high for them, they put you on to motorbike trader.co.uk (looks like the same company) also not interested.
Anyway, I contacted bikesanctuary.co.uk, they didn't respond at all initially, when I phoned them they claimed their own website form had gone to their junk folder. Finally got an offer from them, about what I expected from a dealer, which I accepted to avoid the c*nts I've been dealing with.
However, piss-up and brewery come to mind. They are obviously a new firm and totally disorganised, so as big a waste of time as the others!
Upshot is that the bike remains available and if anyone on here is interested, they could get a very good deal!
