He became a particular fan of Chip Brunner's 1965 Ford Mustang GT.
Robert is also a fan of model cars, having quite the collection of miniatures and collectibles.
He decided to combine these two enthusiasms.
He ordered what he calls a 'clear body' Mustang GT from HPI, a well-known purveyor of model cars. It is a nitro-powered remote control car with four-wheel drive, no less.
He enquired of Chip about the exact paint colours were on the original.
Diamond made some of the decals himself, and had a graphics company make the others.
The thing that looks like a jet engine on the model's roof?
That's a helmet-camera!
Would love to see some of that video...
His fellow competitors thought that finally, here was a Mustang Chip could drive!
