falco, you can forget about the 166 handling as well as the 156 you're driving right know. 156 outclasses the 166 bigtime as far as handling is concerned. Direct steering, communication with the steering wheel, communication with the road. If you do a lot of motorway miles though, the 166 is the car to go for. As said previously, you'll drive a less ordinary car than a 5-series (which is basicly the Golf of the rich people...). If you wanna buy new, you may wanna await the facelift though, which will be released in October in Holland.
