I've owned my Smart Car since June of 2008. It's gray with black trim - and it's a convertible!!!
I'm still getting used to it, but I've had only minor problems with it - that is until a few weeks ago....
One morning I tried to start it up and the battery was dead. It had been in a heated garage, and I probably hadn't driven it for a day or 2. I called SMART USA and they dispatched a mechanic. This guy had never seen a Smart Car, but between the 2 of us, we managed to find the battery! He gave it a boost, I let it run for a while and drove over to the service center, which is close to me.
After working on the car for 30 minutes they told me that the cable to the negative side of the battery had been loose. They fixed it???? and sent me on my way.
This morning I tried to start up the car, and, once again, the battery was dead as a doornail. I called the dealership and I was told that this is becoming a very common problem with Smart Car batteries. (My neighbor's daughter has had the same problem.) His suggestion was to buy a more powerful battery. Meanwhile, I called SMART USA and they're dispatching a truck to tow the car to the service center.
