Renault has made some pretty nice cars and are a good seller in most countries. I've rented them in Europe and was impressed with them.
Dauphine was designed for a different market as was the 2cv (or cv2) they did what they were designed to do. Inexpensive transportation for people living in countries that did not an Interstate Highway System and with gas prices about 10 times the price we had here. They were used for picnics on the weekend and were lucky to travel 5000 miles a year. The owner in Europe maintained their own cars, from oil change to tune-up to valve jobs.
A book published in Europe in the 50'60s, "High Performance Cars" listed the Dauphine. I was surprised.
I do have a different view of cars than most. A tag on my Subaru says, "My others car is a Ginetta" (it a 1965 G.4).
