My reasoning for them is this....I want to like the looks of my car, but I also want the majority of people to like the looks of my car. Right now in STOCK form, people like the looks of it. I can guarantee tho if I put on a set of even high quality(from far away who can tell the difference?) altezzas, there's a lot of people who would then look at my car and say "riceboy", or think it looks lame for me to just follow something that is way overdone already.
When it comes to appearance things, I prefer to keep it simple...if you own a Protege, P5 or an MP3, you've already got a nice car and I don't personally think some altezzas will add to the looks of the car, but it will definitely make some people think that it detracts from the look of your car.
