Though a handful of famous models tend to occupy the spotlight, there are tons of very cool yet overlooked muscle cars - the kind of underrated muscle cars people would love to own. It is likely that most of those underrated muscle cars will be worth a lot of money in the near future.

10 1962 Plymouth Savoy Super Stock

To most people, Plymouth is the manufacturer of very bland sedans and mini-vans. The now-defunct carmaker went down the same slippery slope as other manufacturers such as Pontiac and Oldsmobile. Plymouth was not always a terrible car manufacturer, in fact, there was a time went Plymouth actually trumped the competition.

The 1960s saw the emergence of several astonishing muscle cars. The Savoy Super Sport is one of those gems. The 413 Wedge V8 produced an exhilarating 420hp, which is faster than most stock cars released in 1962. The Savoy Super Sport shared the same engine with the Dodge Dart 413.

9 1964 Pontiac Banshee

When people think of the automotive industry of the 1960s, the picture oversized sedans painted in pastel colors. Though it is partially true, American carmakers were also busy creating some of the most insane cars ever. While other carmakers were competing mainly against domestic players, Pontiac was working hard to come up with a Ferrari killer.

Originally labeled as the "Mustang Killer," the Banshee prototype could have taken on any Italian sports cars of that era. The car was originally supposed to rock a V8 that would produce anywhere between 190hp to 250hp. However, it is well-known that several Pontiacs inherited Chevrolet engines - imagine a Banshee with the L88 engine. The Banshee was sold at auction for a calming $750,000.

8 1966 Oldsmobile Toronado

Oldsmobile cars were some of the classiest vehicles ever made in the 1960s. Cadillac is often portrayed as the best domestic luxury cars, but Oldsmobile was not far behind with very racy and elegant vehicles. The Toronado truly embodies Oldsmobile's golden age.

The Toronado seems to have borrowed the fastback of a more popular muscle car. While the back end of the car is stunning, its front end is truly gorgeous! Under the hood is a 425 V8 that develops 385hp. The Toronado is not often looked upon as a classic muscle car, but its engine and design truly prove otherwise.

7 1968 Oldsmobile Hurst Olds

Oldsmobile used to make some great cars. Some of them were both classy and fast. A vast portion of gearheads are not looking for all the luxurious bells and whistles, they want muscle and muscle only. There are plenty of cars that can provide power, and not all of them are as underrated as the original Hurst Olds.

Recognizing a Hurst Olds is quite simple. They all inherited the grey and black two-tone paint job. Based on the Cutlass and 442, the Hurst Olds is a true monster. Its 455 V8 was factory rated at 390hp. The Hurst Olds is highly underrated simply because only 51 units of the Sport Coupe were manufactured in 1968.

6 1969 Chevrolet Nova SS L78

Some of the most iconic muscle cars were manufactured by Chevrolet. The Corvette was considered a high-end muscle sports car ever since its inception. The Camaro was labeled as a "Mustang Killer" ever since it was fitted with a 350 engine. Chevrolet's cars tend to always live up to their reputation, but some, such as the Nova SS L78, deserve more recognition.

The Nova L78 ought to be among the muscle cars that will last a lifetime. It is a sturdy car that is also equipped with an engine that will knock your socks off. The regular Nova SS is equipped with a 396 V8 that cranks out 350hp. Not bad. The L78? Same 396 V8, but with a power output of 375hp.

5 1969 Ford Torino Talladega

Ford, among other carmakers, must produce a specific number of certain models in order to compete in professional racing. Over the years, several limited-edition vehicles stemmed from the need to compete in NASCAR. The Ford Torino Talladega, as the name indicates, is a masterpiece made for the track.

The Torino is one of those muscle cars that make the best daily drivers. It's reliable, but also fast. The 427 V8 produces 335hp, which is quite alright compared to other Ford muscle cars manufactured during that era. Given the fact that only 500 units of the Talladega edition were made, it is among the most sought after Torinos out there.

4 1969 Pontiac Grand Prix

Pontiac has manufactured some of the most outrageous muscle cars. The GTO, for example, is one of the coolest Pontiac muscle cars ever made. That is not where the story ends. Despite the trouble the domestic automotive industry was going through during the 1970s, the Trans Am was still able to pull it off.

The Grand Prix is nowhere close to being one of the worst Pontiac muscle cars to ever touch the tarmac. Far from it. Thanks to its 455 V8, the Grand Prix is capable of developing up to 390hp. The Grand Prix was definitely the more classy muscle car offering from Pontiac. Unfortunately, it never received the attention it truly deserves.

3 1970 AMC Rebel Machine

AMC is such an interesting carmaker. It is unsure what the goal of the company was. They were manufacturing somewhat decent muscle cars, but at the same time, they were also positioning themselves as a producer of slow and boring family cars. However, when AMC did build muscle cars, they build something very impressive. The Rebel Machine is the perfect example.

From the outside, the Rebel Machine is quite bland, which may explain why the car was never among muscle heads' favorites. Despite being equipped with a 390 V8 that develops 340hp at best, the Rebel Machine could not really differentiate itself from the competition. As a result, the Rebel Machine was quickly forgotten (like most AMC cars, really).

2 1970 Mercury Cougar Eliminator

Mercury manufactured several very successful muscle cars. The Comet, Cyclone, and Cougar are among the most popular. Mercury's success in the 1970s seems to have been a fluke. In the 1990s and 2000s, Mercury ruined every single car it touched, including the once iconic Cougar.

The Cougar Eliminator is one of the most badass muscle cars of the 1970s. The reason it is featured in this list is simply that other muscle cars took the spotlight away from the Cougar. The GTO, Mustang, and Camaro were the name of the game. Not the Cougar. Despite the 428 V8 found under its hood, its 335hp was not enough to conquer the hearts of muscle car fans.

1 1970 Plymouth Duster

Sometimes, carmakers release vehicles that simply do not sell. Plymouth was a company that was fully aware of that. Following a streak of ridiculously awful vehicles, the company understood that some models just needed to be discontinued. They were not the only ones. Dodge made the same mistake with the more recent Dodge Magnum Wagon. The Duster faced the same fate as the Magnum.

The Duster is one of the coolest obscure muscle cars. As the vehicle was only produced between 1969 and 1976, the Duster was one short-lived muscle car. The Duster was not the fastest muscle car out there, but it sure looks good. At the best, the car is equipped with a 340 V8 producing only 275hp. It is quite understandable why the car was quickly forgotten.
