9. Shelby Series 1
After the success of the Viper, Carroll decided to return to the sports car manufacturing business with a new project. His idea was to introduce a retro-styled car. It would be a power roadster with sharper handling, more direct driving dynamics, and a modern drivetrain. The idea materialized in the form of the Shelby Series 1. It was a world-class sports convertible and the only vehicle Shelby ever built from the ground up.
They unveiled the Series 1 in 1999 and it featured a gorgeous roadster body. Its low silhouette and design went back to the mid-60s. However, under the body, everything was new, including the Oldsmobile 4.0-liter V8 engine delivering 320 HP. Since the car was light, the performance was impressive.
In fact, accelerating from 0 to 60 mph took only four seconds, which was fantastic for the late ’90s. Unfortunately, U.S. regulations regarding car manufacturing forbade Shelby from producing the Series 1 as a regular model. They only allowed him to build it as a kit car, which he refused. Due to limited availability and high price, they only made about 250 of them up to 2005.
