do the trip rruk. very enjoyable, go to south of france regulary, nice leisurly run, stop overnight in Valance Sud,m the arrive in Canne about 11.00 am
diesel on motorway around E1.60, but in supermarkets low sulpher is around E 1.41 per ltr.
motorway costs about £130 return so not cheap, bur very rarely see road works or have traffic jams, as speed limit is 130km per/hr (80)mph travel is quick.
as they say near where I am "do it man "
