I'm sorry guys but after 2 and a half years of fun on my SV

I'm thinking of getting a Z750.
The nearest kawasaki dealer to me is WheelPower in Raynes Park. They're not the best deal but am inclined to go with them cos' they're local. The things is I don't know anything about them. The set-up there looks ok but the salesman comes across unintersted and a bit of a plonker.
So has anyone got any good/bad stories to tell ?
Cheers

PS is the z750 the right bike to go for ........ what do you reckon
