Hi John!
Wellcome to Autopuzzles!
I've been in San Marino few times and it's amazing how such a small place had more than a car-maker....
I'm sure I have some info about Epocar in my magazines but nothing compared to what we can have from you!
I'll be very happy to know more about your father's car, and if you have more pictures of it, please post them.
I'm sure you know there is another 'Epocar' that builds retro cars (Conte and Countess), based in Serbia.
Ciao,
Francesco PJ
