Ian Callum’s Jaguar Mark 2 goes in to limited production – costs from £350,000

Ian Callum’s Jaguar Mark 2 goes in to limited production Jaguar designer Ian Callum has worked with Classic Motor Cars Limited (CMC) for more than a year to produce his perfect Jaguar Mark 2, and it’s been so well-received it’s going in to limited production.
