This is a single MERCEDES aluminum wheel. It's an original wheel for a W124 or W201 from the 80s or early 90s. It's a 15x6.5 inch Factory 15" Rim. It's not perfect, but it's in good condition. Perfect for a spare or replacement of a damaged rim.
The lug pattern is 5 on 112mm which should fit on most mercedes cars as well as Audi.
