Hi Guys here is some info for u if you ever need to get windows done cheap, I know because I was a glorified window cleaner, read Tinter.
First know that a Precut (the film cut out ready to go on the car,) only costs bout 80 bucks for a 4dr sedan
Second if you can cover a book... remember school days? you can tint a window (maybe just get an expert to do the rear screen) wont cost much if you have the film
Thirdly the process isnt expensive its just soapy water, shampoo actually and VERY clean glass
Also just for interest sakes know that the darker the film the less the time it takes to go that lovely shade of violet and bubble like a bastard... I dont know do bastards bubble? anyway it wont last long, make sure the film you get is metalised and not a house film (yes the tint is different to automotive films and darker and this is how some shonkeys operate cheaply) the adhesive is not pressure sensitive (if you press it it sticks) so once you wind down your windows or it starts to come off it will keep coming off.
Also finally if you are considering going really dark or illegal ( which is under 35% light transmission ) try driving at night with your sunnies on, its a pain in the arse when you have to wind your window down to see at an intersection it maybe better and cheaper to just get some dark seat covers believe me this works.
Any way my two cents!!!
