14. Oldsmobile Rally 350
To fight the tightening regulations that were slowly destroying the muscle car class, Oldsmobile decided to introduce the bright yellow Rally 350 model. It was a clever way to avoid high insurance premiums with a smaller, but still powerful 350 V8 engine that produced 310 HP.
Other manufacturers introduced similar models, but the Oldsmobile Rally is the most famous due to its unmistakable appearance and that eye-catching yellow paint. However, the Rally 350 wasn’t a big success on the market despite the clever engineering. Olds only produced 3,547 examples in 1970, making them rare today.
