Hey y'all....just got rid of my 93 civic ex that had 245,000 mi on it and traded it for an 03 4-dr civic lx with only 25,000 mi on it. It was a Honda certified vehicle and all that and I was wondering if there were any kind of bugs or problems to watch out for on these newer civics? Also, is it possible to upgrade the head units in these?? Thanks guys and sorry I havent posted on here in a while!!
