Just.make sure your door is wider than 16', it's very hard to park two vehicles side by side with a 16' door unless they are VW's...

Funny you mentioned 16 feet. The Metal Garage people just sent me an email that says their widest door is 16' and $1700. They suggested framing the door and installing my own as an option for a wider door. I don't have that skill set.
Update: I'm leaning towards one of the all metal garages 24 X 25. The concrete pad for the garage would be poured first. Smooth finish for easy cleanup.
Then have them put up the all metal garage.
Later come back and pour concrete with a "broom finish" for all the outside area so it's not slick and dangerous when it rains.
That plan means some delay as to when I can actually start using the garage because the outside concrete would need to cure before driving on it. That will give me some time to organize the inside. The lift would go in mid summer.
