Muscle cars are some of the most defiant and powerful vehicles on the market, and some are better-looking than others. Around 1949, the first-ever muscle car was made. The Oldsmobile Rocket 88 was the "OG," and was the first full-sized model to hit the market. Following the notable appearance, the muscle car began to take over the world and the hearts of car owners.

There have been some incredibly capable and attractive muscle cars produced over the years, while there have also been some that we can't look at for too long with a straight face. Here are some of the best-looking and questionably attractive muscle cars over the years.

Ford Mustangs are, and always have been, some of the best all-around performance cars ever produced. Introduced in 1969 by Ford, this Mustang is an absolute stunner. The car is home to a 7-liter, Ford 385 engine, this car is a beast.

Packing 375 horsepower and roughly 450 lbs of torque, who wouldn't want to own this car? The looks of the Boss 429 are everything a car owner could want. With a wide front and husky tires, this Ford will have everyone's heads turning.

Available for five years starting in 1970, this muscle car is a unique one, to say the least. While it isn't uncommon for vintage muscle cars to age like fine wine... it's hard to say that about this Ford. With a plastic hood and very bland exterior, it's hard to ever think of this ride becoming one to add to any collection. Not to mention the top speed is only 113 mph.

8 Best-Looking: Dodge Charger SRT Hellcat

Claimed as the most powerful muscle car ever, this Dodge practically created its spot on this list. Home to a 6.2-liter supercharged Hemi V8 engine, the car can produce 707 horsepower and a top speed of 196 mph.

The Hellcat exterior looks like a machine. With the ability to purchase a wide-body kit, custom hood vents, tires, and an amazing sunroof, it's hard to find another muscle car that can live up to the capabilities of this vehicle.

7 Funny-Looking: Mercury Cougar

The Mercury Cougar was produced from 1967 to 1997, and again from 1999 to 2002. The third-generation model was manufactured in the '70s, and in all honesty, there is very little that is charming about this ride. It is almost as long as a fishing boat.

With the intent of appealing to the "rich man," the looks of this ride are far from luxurious. Producing only 158 horsepower from a V8 engine, this should be considered more of a family car rather than a muscle car.

6 Best-Looking: Chevrolet Chevelle

A list of beautiful muscle cars would not be complete without this beauty! The Chevrolet Chevelle was one of the most successful models for General Motors, from 1964 to 1977. Producing up to 375 horsepower from a mighty V8 engine, the roar of this Chevy is like music to our ears.

With a hard-top and soft-top option, the styling of this car can fit anyone's needs. With its long front-end and classy looks, this muscle car is nothing short of incredible.

5 Funny-Looking: Buick Regal Sport Coupe

During its production years, this car was greatly classified as a "good car", although most people were not fond of the very stale styling. It is easy to say that this vehicle may resemble Buick's rough beginnings until better muscle car models began to be produced.

There is nothing special about the shape, the interior, or the performance as it resembles the regular numbers of old V8 engines. You don't hear much about this car anymore.

4 Best-Looking: Dodge Challenger SXT

Via Guide Auto

If a car could be both lean and full of muscle at the same time, it would be the Dodge Challenger. If it was based on looks alone, the combination of retro but full of power would be the perfect combination as well.

Producing over 300 horsepower, this Dodge is full of power. The spacious cabin inside is just a plus, as well as the 18-inch wheels that take the appearance to a whole new level.

3 Funny-Looking: AMC Gremlin GT

Via Barn Finds

This ugly looking muscle car was produced in the '70s. Producing only 120 horsepower, the performance abilities on this car were slow and underdeveloped. The long front end and short, stubby rear was a very contradictory styling choice, that was not very wise.

This AMC definitely takes the underdog title when it comes to muscle cars, and the almost frail appearance says it all.

2 Best-Looking: Equus Bass 770

Via DriveZing

Produced in 2014, this muscle car is easy on the eyes. Thanks to Equus Automotive, it was fully hand-built in the United States, which is a huge milestone. Equipped with a 6.2-liter LS9 supercharged 90-degree V8 engine, this beast produces 640 horsepower and a top speed over 200 mph.

With a price tag starting at $250,000, it is no surprise that the looks this car gives are unmatched. With a long-nose, snatched rear, and a pure leather interior, what's not to love? The nostalgic appearance of a classic muscle car is enough to make anyone's mouth water, let alone this beastly character's appearance.

1 Funny-Looking: Chevrolet Camaro Iron Duke

Via SpeedDoctor.net

The very first four-cylinder Camaro does not hold a top spot in looks. Sometimes great performance and speed can outweigh appearance, but that's not the case for this Chevy either.

In fact, it was one of the slowest Camaros ever made, only producing 92 horsepower. The body on this ride is very oddly shaped. This Camaro won't be on our wish list any time soon.
