It's a slow day at work, so I looked up the car... It could just be the angle of the photo, but it does look like the bumper and edge of the hood do not quite line up evenly. One of my '99s is like that and it had both airbags blown when I got it. A good collision shop can fix it at a reasonable cost, but I haven't bothered (yet).
Again, I'd recommend a good PPI to figure out if there's an issue. Overall, I though the car looked very good in the ad and if there aren't any surprises, $15k isn't bad.
