Minimum width for a 1-car stall with lift?

[achillesb]

For those who said a single 18' door would be better, I think it would work, I drew it out in adobe (see below). I think it might be tight to get the cars in around the lift post, I would likley have to stagger both vehicles which makes side storage tricky. What do you think?
