The French Riviera might be a playboy’s paradise, but for petrolheads, the mountains above the Mediterranean coast have some of the world’s greatest driving roads. Jethro Bovingdon starts this episode of Petrolhead Planet on a famed rally stage close to Monaco where he meets the first BMW M3. His route then takes him higher into the Alps, to the Route Napoléon and along the Gorges du Verdon. Can the 30-year-old icon still cut it? A special guest, rally and Dakar legend Ari Vatanen, is out to convince Jethro it can. But our host might only have eyes for the E46-generation M3 CSL, which he has a rendezvous with atop the lunar landscape of Mont Ventoux.
