Hall was on the Miata project from very early on, and one of his most fascinating stories is how the convertible got its shape. The droptop wasn't necessarily going to be a rear-wheel drive roadster. There were both front-wheel-drive coupe and mid-engine concepts being considered. In fact, the classic look of the NA generation was the least favorite of the three at the sketch stage.
Hall comes off as a jokester hiding a genius mind. He has a fountain of information in his head about what a Miata should be, but it all comes down to "less is more." However, he admits that it's easy to conceive that idea, but it's much harder to actually execute it well.
