Jim Pritchard works all over the place; if it was me, I'd rather pay travel expenses for someone I know and have used before, rather than someone local to the boat.
I don't even use the local dealers for servicing, let alone a pre-purchase inspection. I guess it depends on how good your French is though, if you're fluent then maybe a local would be ok. I'm not, and I'd rather use someone I know and can communicate effectively with for this sort of thing.
