In the old days, cars were often both. I happened across this image of Jean Bugatti, photographed here with the Bugatti Royale 'Esders' Roadster - he was the son of Ettore and designed this version of the Royale before being killed while testing a factory car at Molsheim.
Yes, that is a 14' wheelbase and a 5.25'track. They sold only 7 cars of which 6 still exist - they had wanted to make a run of 25 but it was the Depression.....
If you owned on today you could probably be happy just sitting looking at it or polishing it much less driving it.
