Tinting is hard. I'd honestly rather rebuild a diff than tint a car. It requires a very clean sterile location which limits airborn particles and is made more difficult if you do not know the tricks like using a banana instead of a squeegee, etc... I've had two discos tinted. One had limo tint (5%) minus the front windows (illegal in colorado) for $165. Also had a 27% tint put on all windows for $195. Both were done by a top tinter. I hope the numbers help. Also ask the tinter for his strategy on the curving rear roof glass panels. The reason I say this is that this window has a compound curve and has to be done with two pieces. If he is good, you will not even see a seam.
