i'm not a teenage girl but if it were my daughter i'd probably replace the manufacturers speaks they tend to blow quick and maybe a CD deck
if you decide on replacing the speakers and stuff i'm a personal fan of the sony explode setups they can be pricey tho
your a awesome parent all me and my siblings bought our own cars my first car was a ford tempo that i spent 300 on it wasn't the best runner but hey it worked
The stereo is easy enough to do. When I was a teen I thought I wanted to be a mechanic so I went to a trade school. I worked for a few years at a ford dealer then realized I didn't like it as much as I thought I would. I also moon lighted at a stereo shop so I can put a head unit and workers installed in no time flat. Sonny explode is good.
