Smarts can be practical
Added: 11th of October 2013
I have been running a diesel Smart for 4 years and generally find it more practical than I expected. It's not at all uncomfortable on journeys of up to 150 miles or so, and the luggage space is adequate for most purposes. As you'd expect it's economical, though not to the level of the official mileage; I have achieved almost exactly 60mpg over 4 years, with mainly urban but occasional longer motorway or cross country journeys. It has some idiosyncrasies (like the need to be very careful to fully engage the handbrake when parked on a slope) and is slow to accelerate, and although it's happy enough on the motorway at 75mph, you shouldn't expect to go any faster. The slightly elevated driving position is a plus; I like the precision of not having power steering and not being too heavy to handle; the stereo system is surprisingly good.
