Also you can do everything by yourself. No need for a mechanic. The motto goes "Hammer, Zange, Draht, kommste bis nach Leningrad". ('hammer, pliers, wire: it'll get you all the way to Leningrad').

And you have to consider, that this car basically never got an update (P 50 and P60 are pretty much the same car, just a different motor. The P 601 was built from 1964 til the end of Socialism. The 1.1 doesn't really count).
