Woudn't the best way to compare them is to allow the manufacturers to each prep a car and then get a "pro" driver to drive both? All on the same day, etc. to keep things on an even playing field.
I nominate you all come to Firebird Raceway and have Bob Bondurant do it. The fact that I live 6 minutes away from track and his driving school facility has
nothing to do with it.
