I recall it didn't work out that well for Big Ron...
Indeed. Forced out a few years later as the F1 team were not improving and sold his 25% stake a few months after that. I understand Ron Dennis is no longer involved with McLaren in any way. A massive fall from grace for a man that made McLaren into what it is today and the face of the company during its glory days on track, but it's also an extension of the fallout between him and another shareholder who he was once friends with.
Despite my suggestion yesterday, the McLaren/Ron Dennis tale should serve as a warning of what could happen if it goes wrong.
Anyway, this is going off-topic a bit!
