1970s Era Oldsmobile Cutlass
This model was originally made by Oldsmobile as its entry into the world of muscle cars. Since the company was struggling financially, it made a lot of last-minute changes in an attempt to make as much profit as possible. Sadly, what was meant to be a promising model became nothing more than a Chevy Malibu with a different name and badge. Even its engine was identical to the one used by the Malibu! Sadly, the V8 engine that the Oldsmobile initially sported was nowhere to be found.
1993 Pontiac Firebird
In 1993, this car proved to be a major letdown. At the time, a lot of car companies had been into name branding engineering. This meant that they used the same car but rename it for a stronger effect. If you look at the Pontiac Firebird and take it out for a drive, you will notice that it is basically a Chevy Camaro with red paint and a different badge! The automaker might have changed its body style, but it ultimately had the same performance that you can expect from a Camaro.
