Whether it is an American muscle car, a European grand tourer, or a Japanese tuner car, many people may feel the need to personalize their vehicles. Sometimes the results are outstanding, but there have been multiple instances when the results were simply hideous. Despite the effort and money invested, the end results were completely atrocious.

Some people have simply destroyed their cars. There are tons of Mustangs car fans would not touch with a ten-foot pole. The same phenomenon has been witnessed with Japanese cars,  such as these modified Japanese cars most people would be embarrassed to drive. It does not always stop at a poor choice of rims or spoiler, however, as there are cars equipped with some of the most awful body kits car fans would like to forget about.

A Chevrolet C10 is a very decent work truck. It does not pretend to be something it is not by exhibiting signs of luxury or power. It is, by definition, a mid-sized work truck that is made to haul stuff. There are some people out there that just do not see trucks that way. As a matter of fact, there are plenty of modified trucks on the road that most people would be embarrassed to drive.

This particular C10 is now considered a muscle truck. Judging by the massive hood scoops, the engine must have been completely transformed and now produces over 1000hp - right?! What is certain is that the truck's multiple spoilers and body kit must really help keep the truck's four wheels on the asphalt.

9 British Tank

The British Empire was once the most powerful in the entire world. It was dubbed "the empire where the sun never sets," and the empire's military was among the most powerful in the world. All in all, the United Kingdom's past gives us an idea of why old British carmakers were able to remain in business for so long.

This Bentley Continental GT could be one of the most expensive tanks ever made. Finding a purpose for this luxurious, door-less tank may be quite the challenge. It's safe to say that from an American point-of-view, the Bentley on tank treads could be a caricature perception of the British military. The only things missing would be a tea kettle and a bottle of milk.

The SEMA Show is the best show in the nation for modified cars, often hosting the most thought-out modified cars. Whether mechanically or aesthetically, these cars are absolute head-turners. However, it is possible for a car to be a head-turner for the wrong reasons. Some car fans may enjoy this 1969 lifted Porsche 911, but Porsche purists may wish to look away from this atrocity.

Though this Porsche could be part of the most awesome pictures of modified Porsches car fans need to see, the fact that it is lifted and Baja-ready may not please the vast majority of automotive aficionados. It must still be a fun car to drive but lifting a classic Porsche can be perceived as blasphemy by a huge portion of Porsche owners.

7 Chrysmaro SRT-SS

The Chrysler 300C has been among one of the most modified sedans. Thanks to its affordability and the availability of aftermarket parts, tuners nationwide have done about everything and anything to the 300C. However, it is quite rare to see the front end of a Camaro on a Chrysler 300C.

Via autoguide.com

This Chrysmaro could have been among the most awful cars built by West Coast Customs. The hideous paint job gives the car an American rice burner feel. This abomination is also equipped with Lambo doors, just to add insult to injury. It is safe to say that this car must be scrapped and never talked about. Ever.

The Dodge Challenger is a safe base for a project. Given its naturally racey style and outstanding performance, it is normal that tuners are looking for the most intricate custom styles to differentiate themselves from others. This Challenger was featured at SEMA. Its abject ugliness struck everybody's attention.

Via favcars.com

Rich Evans' Challenger is the kind of Challenger no one wants to be associated with. There is nothing about this Challenger that should be considered as a good idea. From the spoiler to the rims, absolutely everything is lacking any taste. The last nail in the coffin is that outdated tribal sticker on the back window.

5 Duke Subaru Of Impreza, STI The Fourth

The Subaru Impreza STI is one impressive rally car. For over fifteen years, the Japanese carmaker has been releasing sport versions of the sedan. Some of them, if not most, have undergone some substantial amount of work. There are multiple modified Imprezas that look absolutely incredible.

This engraved Subaru Impreza sure is very peculiar. It may not please everybody, but it is very original. Most people may find the car ugly. That is quite understandable. However, it would be interesting to know how the patterns were engraved in the car. The fad may never pick up, but at least you got to see it.

4 Stanced, Bro

The Toyota Supra was once a trim level offered on the Celica. Over the years, the Celica sort of lost what made it special. The latest editions were quite slow and boring to drive. As a result, they did not receive the warm welcome their predecessors did. However, that did not prevent car fans worldwide from customizing it.

It is quite difficult to understand how this Celica can be driven around without getting completely destroyed. Hitting a pothole must end up costing thousands of dollars. This Celica is one of these stanced cars automotive fans wish they could forget. Stanced cars are very popular in Japan. Though the trend is picking up in the US, people know exactly why it is not rapidly taking off.

3 The Rich Evans Treatment

Rich Evans has demonstrated time and time again that money cannot buy taste. Mainly focusing on American muscle cars, his shop has churned out some of the ugliest modified muscle cars ever. Some people may appreciate the cheap Mad Max-style. Beauty is in the eye of the beholder after all.

It is safe to say that the owner of this car has their own definition of taste. The multiple and useless hood coops are truly atrocious, and the front bumper seems to have been made after watching an episode of Power Rangers. Rich Evans' creations are often quite puzzling.

The Mazda Miata MX-5 is among the greatest road cars made by Mazda. It has been at the center of the JDM scene for decades. Thanks to its modularity, the Miata underwent anything car fans can think of. Renowned internationally as the best Japanese roadster, it is unarguably both the most affordable and popular car ever produced by Mazda.

Via motor1.com

Since this Miata's steering wheel is on the right-hand side, it must be based somewhere in the United Kingdom. Even without looking at the steering wheel, it is possible to figure out the origin of the vehicle. The poppy themed paint job screams "United Kingdom." The British eccentricity is beautifully added to this customized race car.

1 Superman

The Chrysler 300C has been used and abused for decades. Often times used as a fast sedan, since it is available with a 6.2L V8, the 300C can be a real monster. Despite its reputation of being unreliable and poorly finished, the 300C remains an excellent base to start a project.

Via motor1.com

This 300C is every tuner's kryptonite. Being atrociously hideous inside and out, this Superman-themed Chrysler is every four-year-old dream. It is astonishing that the car was allowed to be showcased anywhere. Super-heroes are fun to watch on TV or on a t-shirt, but this atrocity on wheels deserves a better life.
