9. Oldsmobile Rally 350
To fight the tightening regulations that were destroying muscle cars, Oldsmobile introduced the bright yellow Rally 350. It was smart to avoid high insurance premiums with a smaller yet still powerful 350 V8 engine producing 310 HP. This model was basically a 442 muscle car with a smaller engine and price. The bright yellow paint was the most exciting feature, along with yellow bumpers, spoiler, and wheel inserts.

It looked like somebody dropped the Oldsmobile Cutlass in bright yellow paint. Other manufacturers introduced similar models, but this Oldsmobile stands out due to its unmistakable appearance. However, the Rally 350 wasn’t a big success despite its intelligent engineering, so Oldsmobile only built 3,547 of them in 1970. Although most Oldsmobile performance cars are well-known among car enthusiasts, they forgot the Rally 350, so it’s very rare today.
