Responding to texases, owner’s size is certainly a consideration but I think the Miata and Crossfire are actually aimed at different markets, with the Miata being more of a “Traditional British Sports Car” and the Crossfire being more of a “Cafe Racer”.
i.e. If I’m thinking about track events definitely the Miata but on a long cruise, probably the Crossfire.
