"My ___ car is a ..." (bumper sticker phrase)

OTHER

Think of the opposite of "this" when describing something that belongs to someone else.

This clue references a common bumper sticker phrase that humorously completes the sentence "My ___ car is a..." with something unexpected, like "My other car is a Porsche" or "My other car is a broomstick." The answer "OTHER" fits because it’s the missing word in that well-known setup, playing on the idea of contrasting a modest vehicle with something fancier or absurd. The joke relies on the listener filling in the blank with their own assumption before the punchline.
