Stock, it's a wallowy boat.
With suspension mods like mine (Koni struts / poly bushings / sway bars), good tires, and an aggressive alignment, it's pretty damned good considering it's a heavy, heavy car. Unfortunately having a lot of negative camber dialed in, which is necessary to kill that huge dead-band in the steering, plays hell on tires. If you don't drive it much, that's not a huge factor-- in my case, however, it has forced me to get less aggressive on the camber, so I'm back to numb steering.
It's still light years better than stock, but coming as I have from the BMW world, driving this car is a bit like f*cking while wearing a rubber.
The torquey engine and IRS make her a blast to throttle steer, and she has good controllability right up to the limits.
