Opel — 2 museum-grade prints across the catalogue. The Opel Kadett 400 sat alongside Manta and Ascona Group B programs as GM Europe's compact hatch homologation ambition — Rothmans sponsorship linking British tobacco branding to German engineering in a livery instantly recognizable on 1980s rally broadcasts. While Audi quattro rewrote traction physics, rear-drive and front-drive Opel specials still earned forest-stage respect through lightweight hatch silhouettes and Rothmans Opel Rally Team service-park presence. The Opel Manta 400 represented GM Europe's most serious Group B homologation effort — a rear-drive coupé developed with Irmscher and Cosworth when Audi's quattro was rewriting rally physics. Jimmy McRae's British Rally Championship success in Rothmans colours gave the Manta cult status in UK rally folklore, while Russell Brookes carried the factory programme through European events that proved Opel could compete without four driven wheels.
