It's a touch underpowered for some of the alpine passes but she did the trick recommend it over a tent anytime having done both! its gorgeous around there, some serious boats aswell! we did from Spain across the whole south coast last year. Cassis is a lovely little coastal town if you end up that far west. Are you driving back? Gorges du Verdon are worthwhile along with areas around Geneva(thonon les bains) and annecy the lakes are warm and unbelievably clear!!
One that we didn't get either, maybe they gave it to them to tide by while they waited for mk4 Gotta be my favorite place for road trips, did Europe this year in a T4 where you heading/been?
