This auction is mentioned elsewhere and this promotion claims that the car is the one he finished 2nd in at Monaco and nearly won!
This is complete bull. The Monaco chassis TG184-02 is still owned by Roger Cowman's syndicate and has been here in Europe since '84, although is up for sale. The car in Argentina is probably chassis '05'.
Senna used '02' up to his suspension from the Italian GP by Toleman boss Alex Hawkridge. 'Hawkeye' was upset that Senna had signed for Lotus for '85 without discussing it first, so dropped him for one race. The team had been a one car operation anyway since Cecotto broke his legs at Brands Hatch.
Therefore a replacement was required for Monza so Stefan Johansson was drafted in from Tyrrell and finished a fine 4th in '02'. Stefan kept the car for the final two races and Senna used '05' on his return, finishing 3rd at the season closing Portugese GP.
Chassis 05 went to the Auto Toy Store in the USA and has been in the Americas ever since.
Johansson was given chassis 02 as the team could not pay him. Roger's syndicate bought the car from Johansson's father several years later and have all factory documents. The car in this promotion is definitely a Senna Toleman but not the one everybody remembers.
Such a cool car, that it was Senna's makes it even better! F1 needs to get rid of the regulations so we can get crazy inovations like that again.
