spent quite a bit of time holidaying and working in France, only ever seen one viper (black gen1 RT) but that was in Monaco
I've noticed France doesnt have many 'sportscars' in general, porsche, ferrari, lambo etc its just full of boring Renault and Citreon, except at the Lemans time when the Brits take over that region

Thats a must if you haven been before. French roads are usually excellent condition espicially the toll roads, where you can put your foot down
Good luck with finding some other French viper owners there must be a few out there.. somewhere
