Mirror Problem

Ok so I just got in my car and went to adjust the mirror and it didn't move. Does anyone know where the fuse is for the mirror or an answer to why this problem would have occurred so randomly? Also, does anyone know how much it would cost to get something like this fixed if I can't fix it manually?

Front Lip

I want to change the appearance of my car (2003 BMW 325i). So I am thinking about getting a Front lip kit off of bavauto.com. I am only concerned that if I get the lip if I will have to be more careful where I go to avoid scrapping it on the road. Also, Do you think this will change the appearance of my car significantly? Or if you know of any other accessories that would change the appearance to look more street please post back.

Supercharger

I have been looking to boost the horsepower in my car, I was looking at a supercharger. It has a good and bad side to it, the good side is that increases horsepower by 100 to the wheels. The bad side of it is that it costs five grand. I'm not sure if I want one yet but it just seems like it would be a significant horsepower booster. I do have one question though, will a supercharger give me engine problems later on if I decide to get one? Here is a link of the supercharger I was looking at: http://www.activeautowerke.com/viewproduct.aspx?id=Product18

paint job

Alright so I have been wanting to get the front end of my car repainted becuase after having it a while, there are little knicks in the paint from the road. Anyone know how much this will cost me and where a good body shop is? My car color is jet black, I don't know if the color is a factor of price or not.

Halo's

I have been just looking around for different parts for my car I came across these halos for a Bmw. I was just wondering how much halos will run me and how difficult it is to install by yourself? here is a link to what halo's look like, I think they look pretty badass on a Bimmer. The halo's in this picture are H.I.D., but I think you can also get them in just regular stock light color as well. http://e46fanatics.com/features/jlevi_guide_files/image026.jpg

Window-snapping sound

I have been hearing a weird snapping sound whenever I roll up or roll down my windows. My friend heard the same thing on his car a while back and a few weeks later his window regulators broke and had to replace them. I was just wondering if this could be what is going to happen to mine and if so how pricey are the regulators with instillation?

Felt lining

Ok so I have been having a problem with the felt lining in my car it is coming undone. My car is only an 03 and this shouldn't be happening. Does anyone know how much it costs to replace the felt or should it be under warranty? Also if I were to fix it myself what should I use to keep it in place?
