Yeah, I agree a great looking car. George Begg's book "When The Engine Roars" paints a great picture of the design and build of these cars, and how Murdoch burnt himself out in building this car. Imagine how well it could have gone if he were in full health.
To my mind one of the best looking of all F5000s was this Begg FM5, which I think was Allan McCullys car? Gavins photo below captures the lines of the car perfectly. Does this car still have the Robin Officer alloy body?
