Production car:
Pre-production
The steering wheel, leather covered dash and handbrake were the showcar additions. I’ve not seen a handbrake handle where the whole lot, including the grip, is covered in leather.

Pre-production

Standard production clocks
Pre-production

Production
Pre-production
Different fan markings, square edge to openings
Cowl trim completely different.
Different camcover on the prototype. Rough looking plastic mouldings, and whats the cable operated round part to the right of the AFM?
