Ok I'll bite. First of all ^ James Rogers, that is very cool! You see potential in the old building that just speaks volumes about what we do, preserving some history and character. I'm sure it will be advertising just by itself when completed. Many people would see the simple solution to just buy the lot, knock the old building down and put a metal sided pole barn in its place (probably cheaper, easier but lacking any character) I'm much more excited about the potential of the old building and what it will look like when you have it fixed up and setup.
As for my own humble setup I just have a 1.75 car garage. I call it that because with the furnace, water heater, and door steps in the left stall you can only fit a very small, short car. My model A fits the bill but you can forget about a modern vehicle of any size bigger than a compact to midsize sedan. My honda civic I recently traded off fit within inches lengthwise. We now have a new Honda CRV that will hopefully reside on the right side and my pickup will stay outside. I can squeeze my F150 in the right side within inches lengthwise yet width is a serious issue with two vehicles inside. Its a tight squeeze!
I spent the last year tearing apart my Model A and doing brakes, suspension, rear end and transmission work etc and my wife was (fortunately) a pretty good sport about parking outside since the Model A took over the whole garage in the process. I also hung some plastic to repaint my rear end and transmission parts. I am envious of people with a lift of any sort, people with air tools, paint guns, paint booths etc. I guess you gotta start somewhere and its not like I'm laying in the dirt either so I do have much to be thankful for.
I really want to slap the builder for not making my garage 3 ft deeper and 3ft wider! I guess modern suburbia doesn't have a need for a garage as we used to know it. Most of my neighbors use theirs just to dump their tons of junk and cardboard boxes etc. Nobody parks inside or uses it for a useful workspace anymore.
