At the end of the program most of the prototypes were purchased back by Citroën's to be destroyed. About 1/3 of the owners however decided to keep their cars. As with many other car manufacturers, plans to adopt the use of the Wankel were abandoned as a result of reliability issues and the oil crisis of the 1970's. Today, the few remaining M35s are treasured by the enthusiast community and for good reason as it is a pretty unique little coupe.
More about this jewel elsewhere on the Web:
I think that the very angular "fastback" profile is part of the attraction.
Orthographic projection provides a great way to examine the lines of the M35.
Front has a familiar resemblance to the more common Ami 8. Fenders amongst the few parts shared.
Interior is an exercise in simplicity. Bucket seats clearly inspired the ones later found on the SM.
The body was assembled by French coach builder Heuliez.
Assembly line of the period a very industrial affair.
Suspension is a mixture of DS and 2CV components (see above and below).
Single rotor 995cc Wankel power plant with all of 49hp is the heart of the M35.
It is obviously a show stopper everywhere it goes...
