Meh. I wouldn't be reading too much into one test at one track - assuming all cars are driven equally well, certain layouts will favour certain cars.
At the end of the day we can choose where we want to put out money (however much it is that we have) down on a car after sampling whatever takes our interest.
For me, I like to have a BMW in my stable. I don't care if something can lap the VIR quicker than my car can, I still don't want to drive it.
