Which body shape is most sensitive to dirt?

My question arises from the title. The background is the fact that I have been driving an SUV model for the first time since now for a year and a half (Toyota Yaris Cross) and I have the impression that this hard-to-do body shape tends to pollute extremely quickly in everyday life (neck area, side skirts and lower door area and this despite the higher ground clearance). Two of my neighbours also drive SUV (VW Tiguan and T-Roc). Ntionelle small cars, which also park in our residential street, get away better (Opel Corsa, VW Polo e.g.). Staircase Limousines there are less and less, but I think the dirt water management is also much cheaper there (BMW 3er, Audi A4 Staircase etc.). Of course, it is quite clear to me that one must always take into account the routes that were driven. Especially outside in rural regions were and are the roads for several weeks because of the harvest time extremely If you’re in traffic jam in the city, you’ll probably have a clean car for longer… even in bad weather. Nevertheless, I’m firmly convinced that the body shape is also clearly decisive, how long a vehicle looks badly cared for or completely crazy. What’s your experience?
