While, there is nothing wrong with making a car look how you want it, don't think that other people won't talk shit about your car. If you like it, who cares what other people say or even think about it, its your car, you drive it, it makes you happy. Some people didn't like my choice of stripes, but screw it, my car, I love them and think they're unique.
Although, personally, I don't mind people modding their car to make a v6 look like a GT, a GT as a gt500/cobra, or a firebird into a transam, etc, etc. I think its dumb when these people go all out and put all the badges, emblems, and any other symbols that really physically differentiate the car. When they pass this line, I don't think they are trying to make their car look cool, they are trying to deceive others into believing that they have a car that is A) A lot more expensive then theirs, or B) Trying to show off that their car is "super fast" because its the more powerful model.
