My 04 TF passes for the London ULEZ so assume that makes it EURO 3?
When I last drove to Italy I went Zeebrugge (sadly no longer possible) then Germany/Austria, but we were heading for the North East. On the way back we did Turin to Zeebrugge via Dijon and Brussels. There were some great D Roads North from Dijon. At one point we clicked over the hour without seeing a single other car.
