I donno bout you guys- but I'm seeing 2 blue boxes (with the nav info Engines, Services, Online Store.... etc) next to eachother. Not sure why that is.
I dont think the graphic up top is TOO busy - I actually kinda like it... but it is probably a little big. It looks fine on my computer but I'm running 1600x1200 resolution so things are a little bit smaller over here... Also with the header image-- maybe make the AFTER DARK TUNING bit stand out a little more... it kinda blends into the background a little more than it should.
I agree with AK about the navigation though-- why do you have all the Home/About/Contact... etc horizontally and the other stuff vertically in that box? It doesnt make sense really... Pick one or the other, and arrange it like AK said-- make it so it's EEEAASSSYYYY to understand.
The text for each section needs a LOT of work. I understand its just thrown together, but if you want a professional looking website you need to have it all look professional- not just some fancy graphics that lead to something I can bang out in wordpad.
I dont think white on black is TOO bad... but again it doesnt look professional... maybe have some tables with colored backgrounds(and borders)... something like that. Do it with stylesheets to make it look nice.
If you're gonna have the header image and that horizontal nav bar on every page, why not put it in a frame?
ALT and META tags, titles for the pages... thats basic stuff you shouldnt be missing man- comeon dont get lazy!
Maybe the FAQ can be arranged better-- some sort of index of the questions or something like that.
Make the link colors (outside of the nav) something other than that fugly blue color. Again, stylesheets!
Re-write that "About" story... I know that might not be your responsibility, but comeon... its pretty corny and again, it doesnt look very professional. "He decided to step up and fill the gap where the Nissan guys were left empty handed. The result? The best and most reliable source for japanese domestic market engine swaps." Tell me that doesnt strike you as at least a LITTLE corny...?
ah ok I think I'm done for now. good work so far though man- really.. Ive got a lot of complaints but only to help ya out. It's a good first draft!
