10 Muscle Cars That Should Never Be Restomodded

The American car industry would have never been admired globally if it were not for its muscle cars. First introduced in the late 1940s with the Oldsmobile Rocket 88, muscle cars have since become a beacon of American hegemony. Although modern muscle cars have adopted features usually found on imports, the classic versions are still the real deal, but can end up being a pain to maintain.

In the last 15 years or so, classic muscle cars found a new life. Amateur and professional tuners, such as Ringbrothers or Rtech Fabrications, turned classics into modernized beasts. These cars are worth hundreds of thousands of dollars and are typically one-off creations. However, even if there is a plethora of American classics that would make great restomod projects, some oldies are better left untouched.

Overshadowed by Ford and Lincoln’s sportier and more luxurious vehicles, several Mercury cars failed to receive the attention they truly deserved.

Dodge released a number of sporty muscle cars throughout the 1960s. These cars came with emblematic engines, such as the 426 Hemi or the 440 Magnum, however, these cars were not necessarily pleasing to the eye. The second generation Dodge Polara is a prime example. The RB trim came with all the bells and whistles a gearhead could ask for, but was simply repulsive. Things drastically changed the following decade.

In 1970, Dodge’s lineup was filled with gorgeous muscle cars. The Challenger, smaller than the Charger, was a great alternative to the popular Mustang and Camaro. Similarly to other domestic sports cars released in 1970, the Challenger came with a more desirable package; the legendary Road Track could be had with a meaty 426 cu in V8 that made 425 hp and 490 lb-ft of torque. With only nine 426 convertibles made in 1970, it goes without saying that this classic should never be modified.

The Monte Carlo has been around for almost 55 years. Though it is fair to admit that the last two generations weren’t exactly stellar, the Monte Carlo is a respected nameplate that lost its appeal as Chevrolet became incapable of building a decent muscle cars during the ’90s and 2000s. Back in the ’70s, the Monte Carlo was a true beast.

To the vast majority of gearheads, the ’80s were all about the foxbody Mustang, the Camaro IROC-Z, or the Trans Am. While it is fair to say that the aforementioned cars were, they were nothing in comparison to what fantastic Buick offered during the same period. The Buick Grand National became a serious contender to other well-established muscle cars.

The Buick Grand National is the ultimate ’80s muscle car, it really showed that Buick had not thrown in the towel. While the Grand National was astonishing, the GNX was one of the most powerful production cars of the ’80s. The turbocharged 3.8-liter V6 makes a staggering 276 hp and 360 lb-ft of torque, which was almost unheard of during the ’80s. The GNX was pricey upon its release, and these days they’re unattainable to all but the most dedicated gearheads.
