Autosport, as usual, breaks the story here.
Wow, seems the Concorde Agreement regarding customer cars versus manufacturer may have played a big role in McLaren backing away from the deal. It seems that if McLaren would not commit to a deal with a team who wasn’t completely clear of any FIA regulation violations, it would have been easy to know this as Aguri has been facing litigation all year from Spyker’s complaint. Where was McLaren’s legal in this? Sheesh.
