I'm trying to understand something now the point is brought up..
How can some one compair a S7 or whatever to a Porsche GT2 or any other road car for that matter. People keep compairing apples and oranges here. One is a purpouse built race car that just might meet street requirements while the other is a production built street car that is preped (as a factory option) for compition in T1 or comperable street car classes? While if you look at the rules they will not take a F1 or a S7. I don't even think they will qualify for GT1 classes.
In terms of who has more racing experiance, that is not the question. McLaren as it sits does not have as much history as Bugatti. Ferrari may be in the picture but do you know to what level? For all you or I know it may be a huge P/R ploy. Untill someone knows exacally what Ferrari has done for McLaren I see no point to even use it in a agument. I don't think any orginal members of the old school Bugatti race R&D people are around but nor is any of Ferrari. Between those two companys you can spit back and forth. Its like Ford and Chevy - have fun beating that into the ground
