Depends on if you push it in the garage from behind or drive it in and need to open the door. Since I live out in the country and don't have neighbors looking over the fence I've been giving serious consideration to buying a 20 ft shipping container to keep my Model A in.
Probably 6'x 14' min. if you put it on rollers and pushed it in a spot. I know bare body would fit between a pick ups wheel wells 4' plus axle and tire width.
OK...I'll be the first. Its clear you dont have enough room. A car like that needs room to breath. Just so happens I got a nice spot in the country, I can keep it for you.
There's a lot of air in there, it will probably fit in a 3 foot cube if you compress it enough. Not that I think it's a good idea... Probably a little hard to uncompress it gracefully. Posted from the TJJ App for iPhone & iPad
