I drove a Buick

Today I brought in my Porsche for service and got a 2011 Buick LaCrosse rental from Enterprise. Drove better than I thought. I can see why some people compare its steering to the new 5-er. Obviously, the Buick is much looser, vaguer, drifty-er in the steering, but in some way it reminds me of the F10 steering, even the hydraulic one in the 550ix. Does not feel like your car is on rails, as did my 2001 M5. It is vague and somewhat loose. But admittedly that's an unfair comparison - maybe the new F10 M5 will feel more like the "Ultimate Driving Machine" than "Joy".....
