"Reynard Motorsport died and Derek Walker bought what was left, so *technically*, going by that rule, Reynards are not allowed either. But somehow, they are allowed - why is that?"
What the heck are you on about?
The Reynard chassis that are left were constructed by Reynard Motorsport.
Looks clear to me.
"Champ Car also has RULES concerning the useage of the ChampCar name and associated sponsors. It has exact RGB colours and exact dimensions and the logos should never be used without the associated sponsors (bridgestone and ford), but yet Champ Cars own site contradicts it. OMGZ PR SPEAKZZZ"
Say what?
Better yet, direct my attention to the RULES and the contradiction.
