I was perusing the internet and stumbled across this bit of cool information.
1987 Team Lotus Agreement - http://legacy.library.ucsf.edu/tid/sdm14j00/pdf
One of the things that stood out to me looking through it was Senna's continuity with the team was directly linked to Gerard Ducarouge. I wonder what might've been had Ducarouge had the budget of McLaren at the time to design the 99T.
