I always wave when out in the Vitesse, and generally get waves back from all Triumphs and others. Not so often from Morgans but I guess they perhaps consider their cars modern, or from pre-war cars. My everyday drive is and Alfa 159, and I give the 'Alfa wave' to others. Usually get a thumbs up from 159, 156, and sporty or older models, but not so much the Mito or Giulietta drivers.
