Cleaning my A4 this morning I noticed black grease coming through the spoke areas on the alloy wheel rim and a coating on the inside surface of the rim. There is also a splashing of grease, black/grey, around the inside wheel arch.
I'm just curious: what's A6 Avant ground clearance? From what I heard, Avant ground clearance is < 5in - is that true? Also, can Avant be had with underbody skid plates? I have Subaru Forester...it has >7in and skid plate for rear differential.
