I own a 2014 Smart electric. It had 9,000 miles when I bought it, and it cost $5,500.00 - I commute in it about 90% of the time. It goes about 65 miles on a charge, which is fine for me, but would be a deal-breaker if you have a long commute. It's a pretty rough ride, and the exterior body panels seem really flimsy - but it is serving me well. A lot of window & seats are comfortable.
