In the 1982 Costa Brava Rally, Beny Fernández and José Luis Sala competed with a Porsche 911 SC from the Rothmans Rally Team, although they did not manage to finish due to an engine failure. Exin drew inspiration from that car for their model reference 4068, which they reproduced using the 911 Carrera mould. The Porsche 911 Carrera was one of the most successful sports cars in rallying in the late seventies and early eighties. Its 911 SC and later 911 SC RS variants were notable for their six-cylinder boxer engine, rear-wheel drive and excellent performance on tarmac, achieving numerous victories in national and international championships.
