Some cars thrive on BaT. Air cooled Porsches, BMW and classic Mercedes typically bring all the money plus some.
Current American Muscle cars usually struggle, especially GM products.
At least the sellers aren't paying Craig Jackson anything
I've noticed that too on BAT, American muscle cars don't often bring the coin that the German stuff does. That was a very interesting auction to watch, the GT still elicits strong feelings 10+ years out from production.
