Mercedes 170 Da OTP 1952
2014 Elf Steden Oldtimer Rally - Wijckel (NL)

This the the rare "Offene Polizei-Tourenwagen" or OTP version of this diesel powered Mercedes. It was a police patrol car and only 530 were made. The German police used these archaic but utterly dependable cars until well into the 1960s.
