Here are two more examples snapped while I've been out and about. The Subaru isn't ridiculous in that it is a rally car (the WRX). It is ridiculous in that it is humongous.
The Mazda Protege actually doesn't look too bad with a spoiler, it's more ridiculous that it's on a Protege. It's a car that's a lot of things, but one of those things isn't needing a spoiler.
