39. Oldsmobile Rally 350
In an attempt to fight the tight regulations destroying the muscle car class, Oldsmobile introduced the bright yellow Rally 350 model. It was a clever way to avoid high insurance premiums with the smaller yet still powerful 350 V8 engine delivering 310 HP.
Other manufacturers introduced similar models, but Oldsmobile is best known due to its unmistakable appearance and eye-catching yellow paint. However, the Rally 350 wasn’t a big success on the market despite the clever engineering, so they only built 3,547 of them in 1970.
