The Smart Fortwo is small on the outside and big on the inside.
The Smart Fortwo that is available in the United States is:
o 8.8 feet long (you can usually fit two Smart Fortwos in an average parking space!)
o 5.1 feet tall (the Smart still has as much headroom as most luxury vehicles!)
o 5.1 feet wide (two six foot, five inch plus people can sit side by side with plenty of shoulder room to spare!)"
Here are the
specs from the
Smart USA site.
height
shed 69 inches = 5 ft 9 in
car 61 inches = 5 ft 1 in
width
shed 70 inches = 5 ft 10 in
car 61 inces = 5 ft 1 in
length
shed ? inches = ? inches
car 104 inches = 8 ft 8 in
How deep is the shed?

From the comparison above, I think it might be a tight fit. It might stick out if it is longer than the shed. If if does fit, it would be a small garage for a small car.
