well apart from the trunions and the stuipiest place on earth to fit a master cylinder for brakes, the minor in my opionon is an ideal classic. Loads of parts avaible and all bolt on.
the Viva on the other hand is a better design, but so much harder to fit new body panels e.g. wings welded on, let alone find them,
But this wasnt why I got inot Viva's... I guess It becuase they are cheap as hell to own and run, unless like me you have fleet status.
