Hey,

It's a very nice, simple, but attractive site.
I love the of colours. They go together great.
I think it would better however, if you move the Time and date down, onto the white part, possibly mean moving the 350z abit to the left.
I like the logo, (text) The (dot) from the com looks great on the "i" by the way.

Maybe nudge the logo abit to the left though.
So it has a equal distance from the logo to the edge of the container all way round?
It would improve it alot in my opinion.
Your welcome text,
You should align it to the left, Or take some spaces out.
Welcome to auto4tuning - automotive web site! Here you will find much useful and interesting information about modified cars.
auto4tuning also has a huge image gallery (over 1200 photos) with babes & cars, BMW Tuning, Fast and Furious Casting, Fast and Furiuos East, authentic photos from Romanian and U.S. automotive events.
See what i mean? It kinda indents it a little bit, makes it look a little bit messy.
Sidebar, the news looks ok, can't say too much about it at this time, as it seems rather empty.
The Google Serach, is it really needed? See what it looks like without, it would make your site look alot cleaner in my opinion.
The buttons look ok, however, behind them, there is that "greyish" colour background?
Try making that background the same as the background on the buttons, (the silver, not the green part)
The links in the footer, maybe bring them down abit, so they arn't as close to the bottom of the container, and center the "Last Updated" text.
Do all that, and i think you site will be a 10. :kickass:
Oh, also, try and intergrate your forum into your design a little bit.
Also, vBulletin and PhpBB are way better than SMF.
I hope this review was helpful.
