Though Schell never won a championship Grand Prix and enjoyed life as a playboy and womanizer, he was highly respected in period; he twice stood on the podium with a best place of second in the 1958 Dutch Grand Prix, won the Caen Grand Prix of 1956, and balanced those with periodic sports car outings. He partnered with Stirling Moss in securing a second place at the 1957 12 Hours of Sebring, and took third place at the same event in 1959. His most notable spells in Formula One came for BRM, Vanwall, and the Maserati factory effort as a subordinate to the five-time champion Juan Manuel Fangio. He also drove for Scuderia Ferrari for a single run at the 1955 Monaco Grand Prix.
