Saloon.

Rolls-Royce's twin-carburettor FB60 engine in an A110-type hull. Automatic, power steering, and power disc/drum brakes are part of the package, as are picnic tables and all other Vanden Plas trimmings: you paid extra for electric dampers (desirable). Rounded-off rear wings and no tail fins. 100mph and 18mpg, but forget all about fun-driving. Good ones can come surprisingly expensive.
