I don't think anyone can answer this question for you. Which boat speaks to you?
A fiberglass-skinned timber boat (as I understood what it is) is not all that horrible to keep up if it is in good condition to begin with. If it is spartan and you're ok with that, then that is that much less in the way of system to repair and maintain. If it is gorgeous and turns you on, and you are ok with the various drawbacks, then why not?
Nothing wrong with Bav/Gen/Ben at all, but 5 - 8 years old is just about the wrong age for one of these, in my opinion, especially if they have been in charter
. This is just the point where systems start to reach the end of their lives and you need a refit
which will cost more than will be reflected in the subsequent value.
I would stretch for a newish one, myself, if I were you. Either that, or go on back to one from the 90's (the Jeanneaus were stick-built until early 2000's -- a huge advantage) which has just been refit
by a loving owner.
I bought an 8 year old large cruising boat which had been lightly used and was in lovely condition, thinking it was a good bargain. Well, so many systems are time-limited instead of hours or use-limited -- I have been replacing, replacing, replacing, and replacing them. The boat was not all that much cheaper than a new one would have been, to justify it all. If I had to do it over again, I think I would buy a new one. Then the only bodges on board will be my own
As someone said above, a modern fiberglass
production boat will sail very well and give you a lot of pleasure. Also a perfectly valid choice.
