Toyota, for believing that it was down to genetics and massively overpaying a racing driver to race for them in the misguided belief that the name mattered.
Mercedes. Showing they will help out teams last minute if they haven't acted like school children all their racing lives.
Nicola Larini - champion for Alfa in touring cars, before they came and ruined the BTCC (imo) and also a relatively random F1 driver
Modena - Larini qualified the bucket of bolts for 5 race and missed out on a point in their debut by 1 place, albeit 3 laps down.
Stefano Modena. One of the next big stars when he made his debut substituting at late notice for the Williams bound Patrese at Brabham in the last race of 1987. Like most 'next big stars' he turned out to be pretty average at best.
