Remember the movie Joe Dirt that came out back in 2001, David Spade playing a redneck stuck in the 80s with a serious mullet. Back in the 80s, the mullet was a popular haircut that coined the term “business in the front, party in the back” due to it being short and groomed in the front, while being long in the back. This saying has since been applied to all sorts of things that look professional on the surface, but are actually wild and fun when more carefully inspected.

These cars are kind of like a mullet, where they look like something maybe you’re not-so-cool parents or maybe even grandparents should be driving while packing a secret punch under the hood. In the car world we call these “sleepers.” A sleeper is just that, something you would sleep on or not expect to be fast at all by looking at it. In this world we know how deceiving looks can be, and these next cars pack a much bigger punch than they look. Take a look at the next 20 cars that look all business but are definitely all party.
