The debut of Ayrton Senna in Formula 1 happened in 1984, with the team of Toleman. The first F1 car he dove was the Toleman TG183B, designed by Rory Byrne. With this car he won his first point in the Grand Prix of South Africa, finishing in 6th place, 3 rounds behind the winner Niki Lauda.
The legendary car is for sale by Cars International. Of course, the price is not known, but definitely you will need to have very deep pockets to be able to become the car’s owner, but you can communicate with Cars International if you are seriously interested.
