How about some conceptual thinking................

Is it fake to put a high quality, shiny paint job on a car that was painted with a brush at the factory?

Is it fake to put a leather interior in a car that originally came with mohair?

Is it fake to lower a pick up to enhance it's appearance (in your view) at the expense of the utility it was originally designed for?

Is it fake to put a mega-watt stereo system in a car that originally came with four tiny speakers?

I think you get the point. Modifying cars to the owners taste has a long and storied history. Fashion trends come and go. Often, one styling statement leads to another. Does it pay homage to the predecessor or mock it? From time to time probably both. There's nothing new nor unique about this sort of variation on a theme.............it's very likely been going on since the time of Og and Grog in their caves trying to "outdo" one another in styling saber tooth tiger hides.
