Dirk Pitt -- had a Voisin as I recall (among other things). My father restored a rather massive Voisin several years ago for a client -- took it to Pebble Beach. The thing was outrageous!
In the meantime, I must say that I desperately want an SP250 -- it would fit nicely with the Tiger. Bloody hard to find one, though, and they seem more expensive on this side of the pond than in Britain and Europe. Perhaps I'll have to find an RHD example.
