I think window tint is actually one of the most functional modifications one can do to a car. Keeps it cooler in the day, helps deter theft (I love how no one can see anything that I leave in the back of my car), helps dim headlights from cars following you at night... and it looks great too.4. Window tint. I did this kind of on impulse, telling myself that the black interior justified it. I'm so glad I did! Never dreamed it would be so aesthetically pleasing. It really makes the car look like a more polished creature.
