Yeah we got ours done at donnyshow. Nice discount as a few of us got it done (ash g, lozz, buzz, gav, smee, me and a couple more i think.)
I paid £120 all round for fader tint which was a superb price. They are mobile and will come to you to do it http://www.window-tinting.net/
See the pic, lol. Fade is silver at bottom to dark at top. Also slightly higher at the back and follows the shape of your cars hips
As for colour - upto you!
