Nice. I was thinking audio, but cars are also interesting...

Some car manufacturers celebrate unique aftermarket modifications to their often older and/or classic vehicles and encourage owners to modify and display their efforts. Some are better executed or more tasteful than others, but the premise is the same. Make it yours.
Many of us have done the same with one or more components. My example would be my VPI HW-19 MkIV with a new motor, suspension and other accouterments.
What's yours?
