My sis has the 5 Auto tranny. I have driven the car a couple of times... gotta say, absolutely do not like the steering.
Its got too much go-kart feel for the lux-sport car its marketed as. In hers it seemed like you never turn the steering wheel past a half-turn in either direction, and thats when making a u-turn

I may be exaggerating a bit about that, but it sure seemed that way. Suspension was very unrefined (for a sport-lux car, if it was a barebones sports car it would be fine).
But take my comments from the base that I drive a 330Ci every day. If I were driving the G every day I could get more used to it and probably would make different comments. But based off a couple relatively short drives in her G, it was very, very easy to go back to the BMW.
My 330Ci is a 5 sp man. I've personally never owned a car with an auto trans, and never ever will have one as a daily driver
Every car my sis has owned has had the same steering though, so I'm sure she loves it, she got a great price on it, and I'm happy to see she got a car she loves. It may just be the hidden mechanic in me talking, but I love seeing people who love their cars.
