Nothing really exciting. I started driving it Thursday, finally got it inspected on Saturday and everything passed. I lasted a day with no stereo. Seriously, driving 60 miles a day with nothing but freeway air noise is quite boring. I picked up the cheapest unit I could through my work which I just happen to like. Just a cheap JVC KD-R210 unit.
One problem with the car I did find was that the air filter was missing a crucial piece so I ended up sucking in nothing but unfiltered air for a few days. I ordered a cheap K&N universal filter.
