But, so far, most micro cars are collectable and the Smart will be the first popular micro car sold across the USA.
There have been others, (we owned a Subaru 360cc, two stroke, 4dr.

). but these were sold in very limited numbers and were seldom seen beyond the West coast.
If the Mitsu "I" kei car had been for sale in the US we may have bought one of those instead of the Smart.
My point in the post is, given the low cost of add ons, buy them in case you have to resell.
