Thanks for the replys, it's a tough decision and it would mainly be for investemt at the moment.
I'd like to equip it to do some small paid jobs as retirement nears but would have to fly under the radar or get a business license. More of a something to do and income suppliment thing than full blown business workings.

I own part of a Tooling and machine shop, I'm not involved in the day to day running of it and we're in the process of selling it. But there are several machine tools we don't use so moving some equipment down would be a start.
I already have plenty of other tools and do machine design and fabrication now, so car work would not have to be the only thing I do.

But, there are two local restoration shops that are turning away excess business so there is some work out there. And lots of old guys with old cars around here that don't want to work on them as well, and they have very few options for getting work done. Most repair shops here now deal in the newer daily driver repair market and need quick turn over. There are not a lot of vintage auto repair shops around as the old guys have died off or retired.
That market sounds appealing, especially if keeping a steady work flow isn't required. Repairs by appointment only? Vintage cars only?
