Car appreciation... the aesthetics, the engineering, etc

Good bit of detective work.

We were delighted when opera conductor and composer Stephen Barlow placed an order for one. His film star wife Joanna Lumley, when asked to contribute to the ‘Courvoisier Book of the Best’ it was the Grinnall V8 she proffered, describing it as ‘a hairy wizard of a car’ adding that driving it was a ‘bat-out-of-hell time!’

I'd say on balance that's too much of a coincidence.
