Rust. There's always the old saying "Honda body's will rust and fall off before the engine dies". It's pretty true so far I've seen. Give the car a GOOD GOOD look over for rust. Body damage can be a pain to pay for someone to fix it. But your not new around here... so you probably know that.
Oh, and a CarFax report... can save you tons of time and headaches and money later on. I'd recommend one to anyone thinking of a new/used car. They are only like... $15-20.
