Please excuse my long delay in reply. I want to share the update with you. 
I inspected this 42 GB with one engine in autumn and to be honest, I was shocked about the condition of this boat. This boat was forgotten for so many years and left there just like taken out of the water. The list of issues and work to do is very long. Thanks to your help I could have looked very good on known issues and locate them very well. It took me many months to prepare the full list and still I find new stuff that has to go on this list when going again and again through the many pictures I shot, reading more stuff and talking to different kind of specialists.
Last days my father could also catch nice meetings with the official GB guys on the Boot Düsseldorf fair and we are very positively surprised how friendly, open and honest this guys from GB are. This prooves that Grand Banks is a big Brand and a strong closed community that holds together well and also old boats are not forgotten.
To get back to this 42, the boat is staying outside for at least 5 years, uncovered under the sun and rain. It is in a shipyard where many boats are grinded. Therefore the paint is full of different kind of particles. Therefore this boat needs new paint for sure if someone will want again a nice looking GB from this example.
The wood is in very bad condition and will need to be replaced on many places, the silicon on the teak decks has cracked and so water can get below the wood and teak decks.
The front hydraulic bow thruster is dismantled on top (i think the motor on top of the bow thruster is missing), there were just the hydraulic pipes disconnected. On the wood around this front bow thruster it can be seen that this part was under water because the paint goes off the wood. So there is something wrong and needs big work on the bowthruster and the wood below the front bed (around the bowthruster), as well.
The water tanks up front seem to have a leak as well so need replacement.
In the bilges (below the engine and on the back of the boat) was water, so definitely water gets inside through the teak decks and probably runs down the fuel tanks.
The engine and other engine components still looked good on outside, test could not be done as boat is outside.
On the fly the instruments and the windows are burned so need replacement. Because it will probably be hard to find this old raymarine instruments these days the whole electronics will have to be replaced.
The engine is a 3126 Caterpillar with 450hp. How many hours it has run could be not checked. The Onan genset has 1530hours.
I can not pay the membership on boatdiesel because they have an error on their site. Does anyone know the costs of new engine parts for this Cat 3126 as follows:
New complete aftercooler
New heat exchanger
If you want to see some pictures I can show you some. Maybe you can see some more issues through your eyes and help expend my list.
Also I have got the right numbers what this kind of boats sell for in southern Europe when in perfect condition. GB 42 made around 2000 in perfect condition with no work needed, with 2 engines, go for around 200.000€ (+- 20000€). This 42 has only one engine and no stabilisers so probably worth even less than 200k€ and this if it would have been in perfect condition. I am very close to making an offer to the owner of this 42, my report is 40 pages long. My offer will be the market price minus repairs needed and then the owner can decide for himself if he wants to let this boat fully rot away or if he wants to hand it over to us, that we save it from a full downfall and disaster. I know this will be a big project for us but we are willing to go fo it if the price will be right. This was such a beautiful boat back then and I am sure that it has the potential to become beautiful again with the right owner, the right work and the right money invested.
