My brother is something of a petrol head and is always messing about with his car. Check out Austin window tint.
Not content to have a motor like everybody else's he's always adding "go faster" stripes, flashy lights, music systems and other stuff to his car, even though it's way past its sell by date.
His latest addition was to add window tint to his vehicle.
He likes the fact that it's more private and people can't just look inside the back seat to see what's going on; it's always great for keeping the car interior cooler when the sun gets hot so fair play to him.
