I don't trust that diagram (never mind the missing exhaust pipes).
I used it before I bought my 3 wheeler to make sure it would fit in a golf-cart bay in my garage. The 1733mm width works out as 68.2 inches, so I thought I would be fine with a 72 inch door opening, but in reality both wheel hubs kiss the rubber door seal flaps as it squeezes in - I get out of the car and push it by hand the last couple of feet. Length seems about right though.
