In only his sixth race as a rookie in the 1984 Formula 1 season in a very wet Monaco Grand Prix, Ayrton Senna finished in second place behind Alain Prost (who had a more competitive McLaren MP4/2) after having started the race in 13th.
It was this performance in the generally uncompetitive Toleman TG184 against drivers like Prost, Keke Rosberg, Niki Lauda, Nigel Mansell and Nelson Piquet that made everyone take notice of Senna.
Now, you can own a piece of racing history as MementoExclusives.com, which bills itself as "the F1 memorabilia and merchandise specialist," has now put up for auction the "genuine race-used, fully running Ayrton Senna Toleman TG184-2 1984 F1 car."
Designed by Rory Byrne and Pat Symonds, and used by Toleman Motorsport for most of the 1984 F1 season, the car is the very same one used by Senna at the aforementioned Monaco Grand Prix.
According to the auctioneer, the car is complete and features the original 1.5-liter, straight-four Hart engine, although it requires a rebuild before it can be run. It also features front and rear double-wishbone suspensions.
So, if you want memorabilia that's indelibly associated with Senna, you can't find anything better than the car he launched his F1 career with.
