Grand Silverline 650

[Paul Beard]

Hi everyone
I am considering buying a ten year old Grand Rob.
It's in good condition and has a 150 HP Suzuki engine - with full yearly service history.
Of course seats and covers need a good clean and maybe repairing, but generally a good looker
Approx 250 hours
A brand new complete rubber tube has been installed - due to an insurance claim (apparently at a cost of 6.500,- euros, the tube was slit open on an iron bar in the harbour).
Stainless steel prop from Suzuki.

Any suggestions please on the approximate used value range ?? Baring in mind the rubber is new, would this dramatically increase its value. ???

I believe a new one of these would cost approx 50.000,- euros.

Any advice, as I have never owned a rib, very much appreciated

Thanks
Paul
