Rank 28 documents the BMW M1 Procar — the Giugiaro-designed mid-engine supercar that BMW Motorsport turned into a one-make championship bridge between Formula One support races and the Group B era's silhouette madness. The Procar series pitted F1 drivers against touring-car specialists in identically prepared M1s with 3.5-litre inline-six power — a spectacle that validated BMW's M division before the M1's homologation story intersected with rally imagination. The master PNG dares a gravel-stage fantasy: Martini stripes, number 2, PIRELLI and BILSTEIN sponsor density, and PROCAR script on the air dam — a mid-engine wedge kicking dust like it belongs beside Delta S4 and 205 T16 on forest roads it never officially conquered. Postage-stamp perforation, 80c denomination, and forest-green borders frame the layout as philatelic specimen art. Wallimilist renders the Martini livery, PROCAR title band, gravel hero, and A rally legend footer exactly as the master PNG dictates — Stage fury kicker and curator copy on BMW's wedge-shaped what-if.
