Had a 1997 535i I loved and couldn't part with. Finally and reluctantly I bought my 550i - shouldn't have waited - it's a simply fantastic car. I look forward to the morning drive more than ever and my SL500 stays parked in the garage. Great performance, handling and comfort as well as all the hitec gismos to keep me happy - and they are useful too particulary headup and satnav. Great. IDrive is simply learnt in a few hours that motoring journos obviously don't give it. Simple - intuitive - and very easy to use regularly when needed.
Engine power, HU display, comfort seats, satnav Did I mention the ENGINE?? It's powerful.
Ride with m sport option is a touch hard at low speeds - soon forgotten when speed rises and handling is superb
