Foxie - that was me! Just a few minutes from home, on the way to Le Mans. Bizarrely, after picking up a friend in Sevenoaks 90 mins later, a bright blue 156GTA SW went past - spotted too late for a wave. That's more GTA's than I see in a 6-month period normally!

Personally I try and eye up Alfa drivers and if they seem to be looking at my car, wave, if not, I don't usually bother, though I'll always wave/flash lights at a GTA. You're the first person to wave back
