Hello. Please help me.

Something seems off in my Pontiac Grand Am site's design.

The header/logo area, IMO, looks fantastic, but below that it all seems boring.
What can I do to make it look better?

I'm not sure what to do...I just know that it looks really off at the moment.

The header is a start. Since you have it centered, it would be best if the skeletal structure of your content was also centered.

Since you're using a black background, I would definitely recommend you make sure that the contrast between the font's colors, and your background are a match, because you don't want your viewers to have to strain their eyes to view your website/read text on it.

The site is based off of DIVs so that's definitely going to make it easier for you to change the width of the website. If you want a specific width make sure that you consider a size that would be appropriate for users that still have 800x600. Maybe 775px, or if you want it to be a fluid width, set a percentage of 75% and make sure you also include a min-width so that it doesn't stretch too far for people that use larger resolutions (like me: I have 1440x900px.)

To center it you would just set margin: 0 auto; which will create equal space on either side of the div (side = left/right, not top/bottom.)

Also, you should specify some anchor coloring in your CSS.
a{}
a:active{}
a:visited{}
a:hover{}

Accessibility recommends that your visited links differ from each other, so make sure that your visited links stand out so users can see what links they've already been too!

Should also look through your css, you've got two errors in it; Might want to clean it up so it doesn't prevent it from rendering wrong in a browser:

make sure you also include a min-width so that it doesn't stretch too far for people that use larger resolutions (like me: I have 1440x900px.)

Just be aware that IE6 and below does NOT support min-width/max-width and you'll have to either use javascript to mimic it, or modify your design.

To center it you would just set margin: 0 auto;

Which works great for all browsers - except IE 6 and below. For those you must also add text-align:center on the body or overall container.

Forgot about that bit about IE6 and margin centering; Thanks for bringing that up.

Yeah.. I can only DREAM that IE 6 would just dry up and blow away really soon, but adoption of IE 7 is pretty slow, so we still must deal with IE's vagaries.

Honestly, the only time I really ever consider IE6, is if the website's statistics has a moderately high number of viewers using it.

For my personal website, I don't get any viewers using IE6, so I don't worry about including a plan b for the website to render properly for them; Especially since my website actually uses max+min width, as well as margin centering (though I actually did have text-align: center applied; I just never think about it when I'm explaining what to do for other people since. Actually, sometimes I never think about IE6 compatibility. Woops...)

So long as it works for the viewers that are the majority; I'm good.

If i were you, i would put more pictures. it will help the site just flows..
