I’ve owned 2cv’s consistently since 1987, current one I’ve had since 1989. Its not my everyday car although it was for around 9 years. Great, fun car but a million miles away from a modern car.
A guy I know had one & always talked about the bad chassis, when they are gone the whole car is shot.
Depends what you mean by ‘shot’. First off if you’re paying £5k for one then you’ll be getting a very good car and it will either have an original mint condition, rust proofed chassis or the chassis will have been replaced with a galvanized one. If you do buy one with a rusty chassis there are lots of specialists replacing them.
EDIT: Yes, the windows. NOthing like driving along on a stiniking hot day, elbow out the window, having it nearly shattered as the window slams into it.
Never had this happen to me, but thats beaten by driving with the roof open.
