I have a 1992 LS 400 which just won't quit but is comfortable and a Boxster which is fun. With the GS 350 I feel I have the best of both worlds, so next week the Porsche goes on sale and the 92 LS becomes my pick up truck. The handling of the GS with 18" summer tire feels honestly as good as the Boxster without the noise and feeling every single crack on the freeway. If it as reliable as my old LS, I will be delighted.
Power, handling, smoothness and quietness along with exceptional quality are the biggest point.
Not yet sold on touch screen but it has only been a couple of days since I got the car.
