The OE guys have ridiculously tight controls on those things, but in the past there have been issues here and there and some "creative thinkers" have attempted sales of less than pristine examples to performance builders at a discount.

It's possible, not probable though.

Other than the above dubious/only remotely possible scenario, they would have caught any issues at the plant. Flagship products like those have got to be right or they go to the scrap pile.
