Mine was freshly washed first thing Sunday morning only to get back from a relatively sensible 30ish mile round trip looking like I'd been performing donuts in the local pig farmers muck ruck

Conditions were pretty good on the M6, dry tarmac, then a few miles on A and B roads which were a bit grotty admittedly but the beast seems to get caked more than I'd expect.
Got the standard 19's on at the mo, no spacers so the wheels aren't closer to the wings so bit confused as to why the "flanks" get dirty so easily

Anyone else notice theirs gets unduly filthed?
