When I was young, my uncle's shop had several different lifts, 2poster, and a 3 different styles of inground lifts, including a scissors lift like the one you showed. The only drawback I remember was having things get in the way, like airhoses and light cords, or parts/tools/debris falling in the channels and causing problems.
Have you seen this option? a single post lift, and it is portable- the base is similar to a pallet jack. I got one like this a few years ago and really like it.
Either way, having any lift - scissor, 1/2/4posts, is gonna be great! Great that you get to design and plan your shop-build! Don't forget, plenty of lighting and outlets including 220v for compressor and welding!
I put 110 and 220 outlets on the main post, under the lift controls of my 2 post. Keep an extension cord plugged in and hung on the post. Welder plugs in right there, ditto elec tools etc.
Looks like a major hazard falling into the hole when lift is extended. How high is your water table near your proposed garage? Is there any chance water can enter the storage space of the lift. I too have a four post lift, very useful, but there are advantages to a two post lift for under car work. I have done a lot of work on many cars, and it is a little added work to have to jack up the car on the 4 post lift for brake or tire work. The four post lift is good for storage too as the suspension is not fully extended for long periods of time.
