ok so i really want a HUD (heads up display) i know that some model vette's and some Cadillac's have them. I drive a 2007 cobalt with every window in the car including the windshield tinted. I think the HUD would look very nice on my windshield especially at night. is it possible to scavange the HUD off a car that previously had one installed and mod it to fit my car? Is there any company that sells them?
