I am not a car fanatic, i won't spend few thousand just to decorate my car in more fancier look. For me, a car just simply means a transport for me, so i really do not know how to comment when my brother said he wants to buy 2 car spoilers for each of his car. Does the car spoiler necessary? Other than create nice appearance on the car, what else it can be provided? Is it can block the wind? I really don't know as i am a car idiot!
