Recalibrate your brain. Go Gallic! There’s very little that’s conventional about the 2CV but there’s also very little than can’t be fixed or replaced extremely simply.
There are only two cylinders to the engine, the suspension is rudimentary but effective, most of the parts unbolt without hassle and just about everything can be fixed with the minimum of tools.
Parts are also widely available and cheap too, though they’re not as easy to access as those of British or American classics. But be brave, go against the flow, and you’ll learn a new way of automotive thinking that’s just as effective as conventional design – and a lot of fun.
