The glass is tinted at the factory but WITHIN the tint. You can either get your tinter to do a 40% tint to make it a total of about 35%, or you can just get normal 35% tint. we tint them all the time and even will tint as dark as a customer really wants to if they want to go darker. It's the Driver's responsibility regarding any defects, regardless of who owns the car. That said, tinting is a very very low risk issue when it comes to that.
Re: headlight protectors, I don't know of anyone running the headlight protectors, but if I see anyone with them I'll chat to them.
