16. 1988-1992 Camaro 1LE
Not a lot of people know about the 1LE third-generation Camaro produced from 1988 to 1992. However, you should blame Chevrolet for that. The 1LE was a very rare option based on the IROC-Z model of the same vintage. It looked like any other Camaro from the outside but its drivetrain options revealed something special (via Hemmings).

The 1LE had a special, shorter differential, which provided better acceleration, bigger brakes, revised suspension, and a lack of options like air conditioning. This resulted in a lighter, faster, and more agile Camaro that was a true enthusiast’s choice. However, not many customers knew about this package since Chevrolet didn’t promote it. In the end, only about a few thousand examples were made.
