Porsche 912 “the” alternative ???

Hey guys, today I had a discussion with my brother again about whether a Porsche 912 is a real alternative to the 911. So I think you can’t drive a 40-year-old Porsche, or a German sports car with so much character in general. My brother said, however, that the “Kisten” are mercilessly undermotorized. So I collect and drive Fiat 124 Spider for several years and am convinced that an old Porsche 912 is a comparable, bedac hte and uncomplicated alternative. Such a simple car can give a savvy screwdriver no riddle, right???? So why do I want to know your opinion on the matter…..my father will next year 70 and I want to give him in good copy for about 15000Euro ……BIT ALL SCREAM WHAT IS INTRODUCTED TO THIS THEMA
