Be careful that the tint is preformed to the curve of the window. All windows on the car are compound curves, and if the tint is not preformed, it will not apply satisfactorily. I got most of mine done for about $150 (all except the front doors and vista glass) about 3 years ago. That figures out to about $30 per glass. I can not imagine the difference to $399 since then. A mobile guy came out and did it at the house.
