Good post. I know I have spent more money on my mods than I should and realistically I may never recover those costs. I also know some of the Embarrassing mods work and we will see some of those things in future production vehicles.
For me I am trying to build a car that looks good and performs at its best (whatever that is)
It all comes down to what you want in a car. Many people just buy a car, put gas in it and go. Others want to modify it to fit them better be it a sound system, paint job, mileage or performance mods.
If you are comfortable or happy just putting gas in your car and driving you would not understand why we do mods. That is OK it just depends on what you want.
