I owned a used 2002 Acura RSX-S and it had rock splatter on the front bumper and it always bothered me, but there wasn't much I could do about it. I ended up getting a brand new 2005 Acura RSX-S and hadn't thought much of the rock chips because it was a brand new car. After nearly 3 years of ownership, the 2005 looked almost as bad as the 2002. When I purchased my 2008 STi, I drove it straight to an installer and had a partial clear PPF installed. Best decision I ever made. I never had a single problem with rock chips, the paint always looked great, but I shorted myself when I got the partial.
Now I have a 2019 M3 and did the full front, rockers, trunk lip, mirrors, headlights... won't ever do it any other way. You can't even tell there's film on the car and the bug splatter comes right off.
I like the peace of mind. The film is a small investment for a vehicle I plan on keeping for a long time. I can't see any of the edges. I won't have to worry about scratches when accessing the frunk and I know the headlights will still shine like new 5-10 years from now.
