I have driven a 2CV (belonging to a co-worker in the UK), and while they are a lot more fun than driving a "muscle car" unless you are on a race track, you certainly don't want to consider two weeks touring in one. For example the practical top speed is only about 40 mph on the flat, and the 0-40 acceleration time is at least 30 seconds. The brakes are almost (but not quite) as fast acting as the acceleration - except when it is raining, in which case "braking" tends to be a philosophical concept, not a practical one.
They are OK to drive in urban traffic so long as you keep away from fast roads and junctions where you need good acceleration to merge into other busy traffic, but they don't play nice with other road users in normal traffic conditions on non-urban roads.
On the other hand, the amount of body roll you can get while cornering at 15 or 20 mph is a unique experience...
The controls are totally different to any other car you will have driven, as well. For example here's how to change gear - note, the gear lever sticks out horizontally from the dashboard, not vertically from the floor!
Hiring one for a day or half a day would be fun, with or without a chauffeur, but not for longer IMO.
But they do have some unique selling points. I once helped use one to transport an eight foot tall potted plant between two houses about 20 miles apart. After checking for any low bridges en route, this was no problem at all. Just roll back the canvas roof from the 2CV, take out the passenger side front seat, put the plant pot in the foot well, and have someone sitting in the rear seat to keep hold of the plant and stop it falling over. Simples!
