Anyone (that's you) who uses inappropriate words like "dumb" when referring to the Smart is actually the dumb one in the group. Play on words is easy for stupid-infused comments, and is no help to the original poster who specifically asked about the Smart car, which he said he likes. Rather than insulting him, just stay away from the keyboard, please.
As for the Smart car, the new generation (2016 on) is a great city car. It has overcome all of the drawbacks of the previous year's version, and is now up to the task. It is strictly a two-seater, but those seats are quite generous. You'll be surprised with the headroom, which, is as useful as your minivan's - just go to a Smart dealer and try sitting in one yourself. My wife was blown away by the actual usable space in the tiny Smart at the auto show. Estimates of the storage space for groceries - once you take out the useless parcel shelf in the trunk, there is a plenty for even a month's shopping for a couple..
