See below:

The Institute gives cars a score of Good, Acceptable, Marginal or Poor on each (bumper) test. Kicking Tires reports, "Out of seven cars, none received the top rating of Good. The Honda Fit, Hyundai Accent, Kia Rio, Mini Cooper and Toyota Yaris all received the lowest rating, Poor, while the Chevy Aveo managed a Marginal rating and the Smart ForTwo was rated Acceptable."

Any stories of how costly it is to repair our bumpers?

 

Depending on the shop that does the repair (how much they charge per hour) it is from $500 - $600 I had both my bumpers replaced as I was rear ended and pushed into the car in front of me. The cost of the repair was more or equal to just replacing the bumper.

 

i think the reason Aveo got a good score is because you cant tell it's damaged after it was damaged.
