I've only had the smart for 2 days, but have driven it over 100 Miles already. Around town, things are great. It's roomy inside, the controls are logically placed, and it has every thing you need for your commute. At speeds over 68 mph, the drag from wind causes the car to bumble about a little. However, it performs strongly at 70, but must be urged to maintain 80 mph. Tailwinds from large trucks toss it a little too. But this vehicle was not designed for freeway travel, anyway. The transmission is a bit jumpy at slow speeds as well. It bucks a bit when it shifts.
I love the size and cute design. Everyone stares and smiles! Some people even laugh at it. I love it because it is small, fun, practical, and efficient. It's comfortable to drive/ride in, but is not a wasteful or excessive vehicle.
Smoother shifting, and make a theft alarm standard.
