Hi there . I have my car Ministerio De Industria in front of me and I thought this was the Log Book as such but I can't find the engine size or power . Now I don't speak Spanish very well but can usually get by . According to my document this car is a 1972 RENAULT-4-S but it isn't obvious what the engine size is or power . I have now got the Motor number which is :- 813-02 and No Del Motor :- 129898 . Can anyone help please .
