In the case of the Westsail pictured it's beat up, forlorn, and a whole lot of work to make it right but there's life in the old girl yet. That said, it is not the sort of project that is suitable for most folk and for most folk it would be the project from hell.
Of course, most folks don't read VolksCruiser or, for that matter, have a clue.
As for my take on such a project it's doable for a lot less time and money than you might expect. Though, admittedly, just the sort of enterprise that would test one's mettle, sanity, and perseverance.
Like I said, not for everyone...
But, just maybe, a good discussion point.
