Nothing.
A reliable mode of transportation. It's a little small for my size, but that is part of the car's appeal. I crashed into another car at about 5 mph and the damge wasn't too bad. I like the car, but worry about the outcome in a serious wreck.
Actually the car stood up really well to an offset front of Echo to rear of minivan impact (only downside was a $3000 repair bill) otherwise it stands up quite well... mine was also rear ended in the fall of 2007 and shoved 3 car lengths from a dead stop by some girl in a Cavalier and that wreck only needed the rear bumper cover replaced.
