Hi. I need a new left side skirt for my 2010 Panamera Turbo and I am apparently too stupid to use the PET



I don't think my car has the XAR package, which the PET calls "Sill covers" and the Stuttcars database (rightly, I suspect) calls "SportDesign side skirts." But does -XAR mean "without" XAR? or with? Why use the minus sign? or is it a dash?

Anyway, these parts seem to have been superseded, but the PET, freshly downloaded from the Porsche site, seems to not have the superseded parts. How does one identify and order the correct parts?
