I've been over 100 many times, up to 130 once..... even for me, that is quite a thrill and a hair raiser. I don't think I'd ever try it again. But I will say this: the car does feel stable up to 120, then it starts to loosen up a bit. At 130 the steering started to feel a little vague. I choose to keep her under 120. I just cringe at the thought of loosing control at that speed. So when that thought enters my head, it usually makes me slow down.
