I use PPF on my M3, super happy with it. I’ve had cars without it and really regretted as the rock chips on bumper and hood etc.. drive me insane. The M3 has 12k miles on it now and is in perfect condition, despite having a truck veer off road and throw gravel at me one afternoon.
That said, I did not PPF the land cruiser. The LC has a lot more plastic on the front, it’s higher up, and it’s a rugged vehicle that will get abused a bit more. PPF is expensive. For me it’s about expectations. I’m ok with the truck getting a bit of patina. I’m not ok with my special expensive toy car getting patina.
