I like it. I almost thought I had clicked on the wrong tab, but it looks nice. The slightly muted colors with dark gray background and the new header, both are winners imo.
The only thing I will propose is some to try texture or gradient or something to the orange as some may consider it drab.
For those of you looking to revert back, or change to any other skin for that matter, go to User CP. Click on 'Edit Options' and scroll all the way down to the bottom. Should be the last, or second to last, option.
Other than the Audi and "97-02" issues I like it. Also, I didn't find the drop down menu to change the skins. It'll take a little while to get used to but I think the site's looks are moving in a good direction.
