Cd claims only are pure marketing manipulation. CdA on the other hand tells us much more.
I'm just the data collector, so I'll leave the actual debate regarding items such as this to you guys

However, perhaps in the near future I'll gather the CdA figures from Sport Auto's supertest

Thanks bum-man, interesting figures. However I can not add that to my list. This is soley for Sport Auto and their Supertests.
