Hi mate,
Your car windows are the same as mine,standard front glass is slightly tinted anyway,approx 15/25%,rear as per order list is approx 60/70% and on the limit of the new law,ie full tint not allowed,esp in the front,so the plod can see you and your get away mask!!!!!
I am led to believe manufacturers can tint,but its very hard if not illegal to get a back street tinter to do it,hope this answers your question and anyone shoot me down if i am wrong!!!!!!
Chris.
