Thanks guys.
In traditional form I read your replies, made my decision based on common sense, and then did something totally different !
Money down on an unreg'd 03 ST4S ABS in Senna metallic grey.
I pick it up next week
Oh, price. Well, not as cheap as the yellow one but less than the red one (after a bit of brief haggling) and a nic discount on any parts
Thanks people. I do value your opinions, even if I don't follow your advice
Cheers,
John.
So who beat me to 'ST04 ESS' then...
