The passenger compartment is equally whimsical: alongside a tribute to the BMW M colors, but also to Spider-Man (the upholstery in red and blue for the upholstery), the cup holder panel bears the signature of Jeff Koons with the same “Bavarian Blue ”of the BMW monogram. The artist also designed the cover of the use and maintenance manual. Each model comes with a certificate, in “Large” format, signed by Jeff Koons himself and by Oliver Zipse (Bmw CEO), which also includes the serial number.
