A Triumph Herald Convertible (516 EOJ) was my first car in 1971. About 4 years later I got another (GVT 722 D) They were always breaking down, MOT’s were a time of fear and the outriggers would rot as you watched.
The half shafts used to snap and the starter used to fail.
The good thing was that the front opening bonnet meant you could sit on the front wheel whilst adjusting the tappets, plugs and points. Every weekend.
Do yourself a favour and get a warm dry reliable car instead and spend all that time doing something you enjoy.
