No worries about the Qs mate, glad to assist. Yes, there is a whole range available, and he went through them all with me. In the end I asked for a shade that was between the two he suggested and he came up with that too. Also, when I was in there, a guy was getting his RX8 done and like you, he asked for legal tints on the fronts. They guy told him that there aren't really any legal tints but he'd fit them at the driver's risk. He also offered the guy a graduated effect from the rears to the fronts so that the difference was blended instead of a marked difference.
After the fitting, he went through all the care instructions with me etc. etc. I dunno much he will charge for all 5 windows though, did you ask?
