I think there is partial cover on this topic on a previous thread on the Comtesse on this forum. An interrogation of the files might yield the info you need. Not least the underneath of Steve Mandells car.
There seem to be quite a number of these cars escaped from France now, so with that and the French owners, there is a pool of interest. Sadly it does seem to be hard work to access a unified source of information, but I am informed that this is the modern, and better way of things, with FaceBook, and other temporary, and fashionable, media dividing the information into a kaleidoscope of dispirate resources. I must say, I was glad to sell my example off, for getting accurate info was very hard work.
