It's incredibly common for Frenchies to buy a car from the UK, and make the initial contact via email. It's what I would do if buying from abroad and my foreign language wasn't as good as it could be. Again, it's something I'd chase up if I wanted the sale, not ignore.
This.
The french guy who bought my Skyline told me that over there most Jap cars cost big money so its cheaper to buy from the UK.
The guy who bought my car needed a copy of the front page of the V5 & also the chassis number so that he could insure it in France & it would cover him to drive it in the UK
