My car looks brand new with its rusted fender and dented doors.

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. "My car is brand new" is totally opposite to "it's rusted fender and dented doors".
