But I notice that, in one breath, he trashed the guy who actually planned to take his car to the track, while in the next breath he trashed people for pretending to be drivers but never taking their cars to the track.
He also laid into the non-stock configuration of the ALMS or Le Mans M3 race cars, but then utterly dismisses the Grand Am series - where real stock M3s actually do compete in the GS class - citing the Kia competition.
In other words the author does demonstrate a bit of hypocrisy, at least at some level of abstraction, and seems to really enjoy ranting.
