I test every machine I get my hands on, completely stock, around the Nordschleife. There I determine everything about the machine that's important to me.For me, its all about The Ring. Almost the only thing I do in GT6 (and it was true of GT5 as well) is pick a car and run laps at The Ring. Occasionally I'll run a few at Spa or another track (and I'm far more interested in tracks as dlc than more cars), but ftmp its The Ring that gets my attention. I'm happy with GT6 because the physics are improved some and they haven't nerfed the Ring experience...
