This is a very helpful map and the price is not bad either. Provence is an easy area to drive around in, but there are many smaller roads and smaller towns with varying levels of signage, so it is very helpful to have an idea of where you're going.
I used this map to drive from Nice to the Luberon region of Provence, from the Luberon to Vaison la Romaine, and finally from Vaison to Arles with many stops and day trips in between, so it was nice to have for reference and planning. Also note that Google Maps has nice maps and I believe it even gives driving directions for France now too, which is nice for advance planning. But once you're on the ground, there's still nothing like a good old-fashioned paper map to help get you to where you're headed.
Bon voyage!
