For a street car, my preference is to leave the body of the car as original and untouched as possible. Which means no widebody.
If we’re talking about a track or race car, then widebody becomes an applicable option… an option that if pursued, must be executed to the full effect. A good example of this is the Zimax MotorFactory RX-7.
I don’t know if the setup of the car in the picture below is older or newer than the above, but I like it more.
