Just wondering if the IS250 has a governor on it. Someone at work said his old is250 (2006, he now has an ES350) cut off at 100mph. I didn't believe this in an IS, so last night on the way home from work (11:45pm, highway was pretty empty) I got on it, and got it up to about 112 before I had to let off because cars were coming up. So is there a top speed limiter? I think I would have reached 120+mph if I didn't let off. I never drive that fast anyways, I was just curious.
