I know a guy that works for a very large multi-dealership in Ipswich who does the window tinting for them through the week, which is charged out to the customer at an average of $600 per car. On the weekends in his shed, he & his mate who also does the same thing, tint car windows using the exact same product (3M) & charge $250 for exactly the same service. He told me that the whole "Protection Package" thing is a big ripoff & there is a huge markup on the products. Late last year, the wife & I bought a new Hyundai i30SR (an absolute rocket) & the dealer did their very best in trying to talk us into the protection package which also included tinted windows. I told them I wasn't interested, but how much just to tint the windows.....you guessed it, $600. I told them I knew a guy that would do it for less than half of that. In the end, the dealership said they could do a full window tint for $300, which I accepted. Go figure!
