10 Sleeper Cars That Will Wake You The Hell Up!
5. GMC Syclone
This GMC pickup, designed to haul tools, is the fastest car GMC has ever produced, accelerating from 0-60 mph in just 4.3 seconds. Powered by a 4.3-liter turbocharged V6 with 280 horsepower, only 2,995 units were made in 1991, making it an extremely rare find.
6. Ford Taurus SHO

The Ford Taurus SHO, produced from 1988 to 1999, offered engine options ranging from a 3.0L V6 to a 3.5L EcoBoost V6, with horsepower from 220 to 365. Despite its plain look, the SHO is a sleeper, with early models accelerating from 0-60 mph in 6.6 seconds, improving over time.
