I just recently had tint done to my 328i. It was about 20%. I decided to go darker because you could still see inside. So I decided to come here and Steve was very helpful with reasonable pricing, since my tint was roughly about 2 months old he just went over it. So my tint was about equal to about 5% he did an excellent job in a decent amount of time especially for it being a Friday. Most definitely making an appointment for my wife next week!!!
