Here are two of the cars that I have tinted. The first one is my own car which is the NSX and it is tinted with 30% rear and 40% fronts. The Diablo is tinted with 20% all around, except for the windshield. It's not everyday that you see a Diablo, but to actually work on it to enhance its looks, I felt honored. I personally wouldn't spend $300K for any car. That's why I ended up with a NSX.
