I have a small hole in the lower bumper grill in the front bumper. Most likely from a stone thrown from a car in front of me. It is really flimsy piece of plastic as I've found out. The hole is smaller than a credit card, though. Now when I return the car from my lease, will MB Financial charge me for it? After all, it was normal wear and tear from driving around, and smaller than a credit card... Or should I just buy the part and replace it? They will probably charge me a lot...

 

A credit card is pretty big...I would fix it, but go to a body shop, not the dealer.
