Whats the difference between Honda Accord Coupe LX and EX?

I'm trying to figure out the difference. Also, i'm looking into buying this car: a href="http://seattle.craigslist.org/sno/cto/848482634.html" rel="nofollow"http://seattle.craigslist.org/sno/cto/84…/a and i'm taking it to the mechanic to get an inspection today. Does it seemed priced right? I've got KBB at about $4300-$5500 depending on condition. It's got paint chips on the rear bumper and there used to be a spoiler on the back that was taken off, so there's tape there now instead and a few lights are out inside the car. From what the guy tells me, it's been nothing but trouble since he bought it 8 months ago and spent about 3 months in the shop getting everything fixed. He says it works fine now. But we are still skeptical. Thanks
