I tint at a shop here in MA, we charge 200 for a full car. It will be much cheaper where you are because it’s more common and the laws aren’t as bad. I would say anywhere from 100–150 for a nice tint job. You can prob find sideskirtz online for around 300 or so depending on the style… Then you have to get them painted and installed, which paint is always crazy money for a car. If you can afford to do that why not just do a full bodykit?
