Congrats on the new GS, please post some pics.
I got the same impression of the GS as you after my test drive, handling is superb, accelaration need more low end torque. The interior is world class, the exterior design is subjective. The only thing I dont agree on is the ride being smooth, the GS350 had the roughest ride out of those 4 cars and I didnt even test drive the F-sport.
