The exact opposite of a ricer. A Sleeper looks stock but is heavily modified to preform better. Sleepers are often,
like ricers, economy cars. Unlike ricers, sleepers can also be regualr sedans or any other vehicle that was not meant to be a preformance vehicle. Sleeper cars are ussually modified with
boost (super or turbochargers), transmisions, and sometimes full engine swaps. Many
people who drive sleepers use them to hustle at the strip or avoid attention from the cops. Many auto makers offer factory sleepers that are a
sport version of the origional economy sedan with very few external changes. Some of the best sleepers of all time came from the muscle car era. The 1972 Chevy
Nova is considered one of the best sleepers. The
Nova is one of the most popular models to get turned into a sleeper. Most sleepers aren't true sleepers because they will have aftermarker gauges visible (real sleepers hide them in the glove
box), racing slicks and loud pipes. A true sleeper will not be exposed until they reach the end of the
track.
Chuck's 1968
Mustang GT500 got spanked by a 1960 Chevy Nomad Wagon. Chuck was the victim of a big time Sleeper when the Nomad lifted the front wheels in the
air and he proceeded to see nothing but tail lights down the
track.
