Hmmm ... I guess it is mostly if you like the look. I don't know about store bought ones as someone suggested, as the fit and finish wouldn't look as nice. I have a hard time right now deciding what I would want to get or not when I purchase a car. I guess I can try to find someplace online as you have to purchase all of the items on my own and save myself from a lot of dealer profit and installation costs!!!

I say ... get them if you have the money to spare!!! Apparently you like them if you are considering them, and it will only have an effect your FE if you turn them on. And you never know, you just might wish you had them one day lol.
