They mention technical spec on 911, 912, standard equipment and accessoires with factory code and price.
Also they compare the 911 and 912 specs with the Carrera 2000GS, Alfa Romeo Guilia, BMW 1800, Fiat 1600, Jaguar E type and a few other cars.
I've never seen these cards before, really happy with them :)
