I had my windows tinted yesterday. I went for 35% all the way around. I figured I'd post some before and after pics for reference in case someone else ever wants to see examples. It turned out a bit darker than I expected, I think because of the factory tint. I like it but might have been oaky with 50% and been able to stay legal! The dark interior and bright yellow exterior definitely help it stand out. The cost was $157 after tax with lifetime warranty.
