Intriguing idea! This one shop close to me, which looks super clean and has a lot of amenities (welders, etc), charges 175/mo, but that's pretty much it. Apparently it's like a gym membership, so you just book the time you need to be there.
I wonder if there are limits, like for instance, can I work on a project and leave the car there 3-4 days, would that be secure (no one messing with it, since they are after all open bays).
If you don't have a garage, like if you live in an apt or condo, this is really a great resource. I agree the hourly rates of 45 does seem a little off, but a membership setup seems a bit more fair if you can use it as much as you need.
I have a garage/workspace at home with pretty much every specialized tool I'd ever need for all my cars. However, I don't have a lift, so sometimes that can get a bit annoying. I know you can pick up some at-home-lifts, but storing it would be a hassle.
Also, being able to use a welder (and this place has classes too and apparently other experts that would be happy to teach/lend a hand) makes it more of a value proposition.
One thing I'm not a fan of are people renting out garages at home (esp if they live in a condo). That seems to be bad all around. I'm also curious as to what insurance coverage (if any) the garage and renters have.
BookGarageTime, PM me, I'm a moderator for another board and a member of several others, might be able to work something out with you.
