A lot of it also depends on where you live and the environment you drive in. The roads here can be rough and there's always gravel and junk on the hwy. We go through several windshields per year. It only makes sense to me to protect the paint. I've taken hits to the PPF that we ll the way through into the paint. If the PPF wasn't there the damage would have been much more substantial. At the end of the day, these are not inexpensive cars.
Even my 4Runner has PPF on the front quarter, but it was a shit job done by the dealer and already in place when I bought the car. And there's rock chips on the leading edge of the hood because they didn't install it well.
