Hi. I'm a little late joining in the discussion. May I suggest that the title (banner) read "Tinted Windows for Your Car." It puts the focus on the tinting, not on the car. Actually, "Custom Tinted Windows" would suffice, as it obviously refers to car windows being tinted. "Your Car's Windows Tinted" is awkward phrasing. Whatever comes naturally in speech, use that. "Experts in Car Window Tinting."

And I would make the word "Tinting" transparent with a gradient over it, to mimic the look of tinting

Edit to add: Great looking site design, though. Very classy.
