Got a new car: what should i do to pimp my ride

[nation]

Ok, so I had a 98 subaru legacy gt, and I held off on upgrading any audio or performance crap bc it was so old. I just got an 05 Legacy GT with 40k miles on it. Everything is stock, it's a sweet car with 250hp and factory turbo.

My favorite color for a car is black, but this is Atlantic Blue. It would cost too much for me to get it painted black, so I'm not going to do that, plus it lowers the value of the car to get it painted.

here's what it looks like



Let's say I have ~1k to spend on improvements. I listen to music basically all time time in the car, so cost effective audio improvements would be nice. Unfortunately I use an fm transmitter for my ipod and I hate the static that always accompanies the music for every station. Incorporating my ipod into the equation is key here.

Note that I can't change my stereo head because it's combined with the ac controls.

I'm assuming I should get new rims too, but they likely would be too expensive.

So, suggestions?
