Many thanks for all the pointers!
It seems if I get a bip or a mono I can still get the white tail fitted, which is a bonus, I expect it will be a pretty penny though.
Ive noticed that the grey 748s seem to be dropping into the low £6000s now, is this a roughly correct estimation? Is there much more servicing requirments for the S than for other models at all?
Cheers.
Ray.
