The fuel mileage may also be a factor for you- the older big V8s got 10mpg on a good day, which I think translates to 23.5 liter/100km. If you aren't going for long,long trips and camping style is more important, then the older tow car would be fun. Post pics of what you find, I'm always curious to see the Euro versions.
I sold my Ami6 a long time ago. I had a 1968
Dodge Dart until recently and now have an Alfa Romeo spider. The Ami was sold in very small numbers in the US, along with the 2CV, until 1966
or so. The DS was sold here until 1972, and the SM, 1973.
