13: 1970 Oldsmobile 442
Oldsmobile is another disbanded GM brand that was at its pinnacle during the muscle car era. Much like Pontiac, there were quite a few Oldsmobile models that have seen values rise quickly on the auction block. Most notably is the Oldsmobile 442, which is based on the Chevrolet Chevelle. Aside from the muscle car aesthetic, there was a lot that made the 442 stand out from the crowd. The first of which is the special-edition 445 CID V8 engine with 400 horsepower and 500 foot-pounds of torque.
Even to this day the Oldsmobile 442 in its original form is a monster on the road. The performance is among the best from a GM vehicle around this period. Valuations on the Oldsmobile 442 have been on the rise, and understandably so because the car has a unique look and feel that’s hard to come by anymore.
