I did a full-body wrap with XPEL Ultimate Plus (minus the roof). My M235 has a partial front wrap and I absolutely hate it. The line running across hood/fenders is barely visible at first, but over time the edge collects grime/dirt/wax and becomes readily apparent. Now it's so visible I'm removing it and getting the full front redone, but whole panels this time.
The rear quarters on the M2 are VERY prone to rock chips since they protrude out so far. BMW knew this would be an issue, hence their feeble attempt to cover them with the inferior film they use from the factory. The diameter of the coverage is insufficient and the quality is sub-par so it yellows over time. Definitely worth replacing.
On a color like BSM, rock chips stand out really bad and would drive my OCD nuts. The PPF is worth the investment, if only for my sanity's sake
