Stone Grey Gravel — 2 museum-grade prints in this palette. 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 Vauxhall Chevette HSR represented GM Europe's most serious British rally homologation effort before Group B regulations tightened — a lightweight hatch developed with Dealer Team expertise that Russell Brookes and Tony Pond campaigned through Lombard RAC Rally folklore and national championship stages. Rothmans sponsorship linked the Chevette to the same tobacco-era visual language Opel Manta and Ford Escort wore across 1980s forest broadcasts.
