Very clean layout on the home page
... here are some things I noticed on first glance when navigating through the site...
When you click the arrow to entire the site, it scrolls beyond the "Who are we" heading. Adjust your anchor placement to be above the heading.
The vertical layout of the services on the home page is pretty stretched out. Perhaps consider doing horizontal columns to consolidate the information into a smaller space.
For the menu in the upper right, you may consider placing your services as the first link, followed by contact info, and then portfolio. Just my opinion here.
On the portfolio page & some of the services pages, you may want to rethink the formatting of the videos & photo galleries. Some of the videos are stretched the entire width of the window and are very distorted, and the top and bottom are cropped off due to the very odd aspect ratio. The others show a preview which spans the entire width of the page, and then plays in only a small portion when clicked on leaving the rest of the space to be filled with a black box. To me, this breaks up the page and ruins the flow/continuity of the site.
Also, and this may be just my personal opinion, but I feel the stationary background and scrolling contents on all services pages is fairly distracting. If you like this effect, I would recommend a less vivid photo for the background to make the page easier to read. The bright blue mustang grabs my attention as I am scrolling way more than the text in the foreground does.
For the paint correction page, there is quite a bit of scrolling involved to view each package. It is fairly difficult to spot the headings as I am scrolling, making it seem a bit unorganized, and again, the full width videos and galleries really chop up the page and make it a little difficult to follow. Again I would consider a horizontal layout that shows your Stage 1 - 3. Perhaps create a new page for each service if you wish to include more detailed information and photos, and provide a link to each service from the main Paint correction page.
That's all I've got... keep in mind it is all just my opinion, so please don't take any of it as anything other than constructive criticism based on my personal feelings
