AN ultra-rare McLaren M23 replica used in the film 'Rush' is set to go on sale - and it's expected to fetch a huge sum. The extremely fast F1 car is only one of two replicas ever made.

The 1976 McLaren M23 replica is set to roll across the auction block on Saturday, November 12, with a guide price between £50,000 and £80,000 (approximately $57,200 to $91,500 USD).

McLaren’s design chief Gordon Coppuck was inspired partly by Lotus’s triumphant 72, but also McLaren’s own M16 Indy car when it came to drafting the M23’s form.
