I love the Smart. It has plenty of room and keeps up with traffic just fine. Maybe because my wife and I weigh less together than many fully grown men. I am averaging 38 mpg, with mostly in-town driving. Parking is fantastic and I am really enjoying the sequential paddle shift transmission. I am hoping (knock on wood) that it will be reliable enough...we will have to see. I don't want this thread to be about the Smart car. It's about efficiency, not the daily driver. To each his own I guess.
Here is a pic of the 914-6 along with two of my past 911s (purple and brown):
