<em>My car looks brand new with its rusted fender and dented doors.</em>
Explanation:
Sarcasm is when someone say something opposite to the actual scenario, to mock something just to make it funny in a delighted way of humor. <em>"My car is brand new"</em>is totally opposite to <em>"it's rusted fender and dented doors". </em>
Clearly his car is old, has rusted fender and dented doors which means poorly managed, but he for the sake of laugh or to make it funny mentioned it a brand new car.
