Hey everyone!

Hope you don't mind me being the classic newbie & posting a question that's been asked 1,000,000 times before (I did try the search but I couldn't get good usable results).

It's time for a new car I've pretty much decided on a 2003 Civic sedan (either left-over inventory or certified used) and just want to get your feedback on any common problems I should look out for. Anything I should look extra closely at while I'm looking for a car? Anything I should watch out for once I've bought one? Thanks everyone!
