Me and my wife went on that 2CV (you know that old typical French car you see in the movies)car ride and i strongly recommend it to everyone. The driver was an authentic parisian (except he was actually really friendly ahah) who told us random stories about the city and France in general. They stopped in front of every main monument to let us take pictures or sometimes even took the pictures for us and the view was just breahttaking. We could stand up (even though the car is so cosy you don't feel like standing up) to take advantage of the view on the Champs Elysees etc... I mean it was such a great typical experience we actually decided to do it again. So the next time they picked us up from the restaurant and drove us around (Moulin Rouge, at the foot of the Eiffel tower, Notre Dame,...), with all the night enlightments etc..+there was litteraly no traffic,we definitely appreciated that bottle of Champagne they let us took in the car. Finally they drove us around Montmartre in some tiny streets and places only locals know so i WON'T hop on any of those touristy buses ever again.
