 While the polyester body panels do not rust, the problem was caused by the underlying steel chassis having almost no corrosion protection.Matra learned from this and fully galvanized the chassis of the Bagheera's successor, the Matra Murena.In March 1973 a team of Matra engineers led by Georges Pinardaud completed the initial design for project M560, which was to be a more powerful Bagheera.
