Well, I just ran this one tonight, and the Cien truly sux0rs. This is my first attempt driving this car, and if it ain't fun to drive at Sears Point, it ain't never gonna be fun to drive. I passed by half a second, but clearly you could do much better with a car that would respond to some of your control inputs. And you have to keep it boiling pretty hard to get power out of it, too. It's not at all like I expected, given how many people seem to like it.
Then again, many people love the C5R, and it's an understeering pig to me, as proved by the other Sears Point mission.
