There was a fade many moons ago naming cars after fish but they tended to conjure up visions of powerful fish e.g Plymouth “Barracuda”, (I have two convertible Plymouths the best by far I’m probably biased ) AMT "Piranha", AMC "Marlin", Opel "Manta", Corvette "Sting Ray" etc Maybe outside chance as a restaurant, food type but doesn’t really have the same impact of the others is it like branding Haddock, Dover soul?
