I will try to go at least through 3 seasons

Meanwhile...
First raceSouth African Grand Prix, 2nd January 1967, KyalamiPracticeLeon's first appearance in his shiny red #4 Ferrari wasn't very fortunate - although he was about to go out first, it took him 10 minutes to leave the pits, stalling his engine numerous times. When he finally got to grips with 312, he couldn't get used to it's fragile V12 engine that would blow three times through the session. However, Enzo Ferrari had enough patience to let him try, time after time. Finally, after spinning millions of times, Leon did a few decent laps before pitting in. His fastest time of 1:27.63 put him in 13th place out of 20 drivers.
RaceIn Ferrari hopes were high. Lorenzo Bandini and Chris Amon qualified on good positions and were ready to attack Brabhams and Coopers. Albertini also was about to get in front of Irwin's BRM. Little did he know, that his start would be one of the biggest crashes of the season.
Leon's start was a disaster - he lost control of his car and slammed into Rodriguez, who clipped Irwin's car and sent him into the bank, launching him in to the air. Irwin hit Surtees on his way down and rolled over. Surprisingly, Rodriguez and Albertini could continue, but not for long - Pedro's suspension collapsed when exiting Leeukop Bend, whilst Leon suffered a puncture in his left rear tyre and parked his car on the outside of Barbeque Bend. His debut not only wasn't impressive, but gave South African press a good reason to dish the dirt on him. Even the old Enzo had to take a few hard knocks, when enraged bosses of BRM, Cooper and Honda paid a visit to him after the race.
However, he not only defended his driver, but assured them of his performance in the next race, that would take place in Monaco.
