The 190 Sl has only recently been added to the Mille Miglia list of eligible cars as it was discovered in 2015 in the Mercedes Archive that the car with number 347 in 1956 was a Mercedes 190 SL driven by the French drivers Michel Bianco / Jean Loup Pellecuer. Starting at 3:47 am they ended up at place 121 with 16h 6 min 15 sec.
