I haven't liked the continuing march to using higher tech and more complicated systems. I can do an oil change and valves on my 07 GSA just about anywhere, and have. I like to travel, and some trips have been long enough that performing maintenance during the trip is necessary I can appreciate that gains can be made in power and efficiency, but for me it's a balancing act with ease of self maintenance. I know BMW needs to compete, just like Porsche did when it water cooled the 911's. I've also read that such measures will be required to meet ever stricter emissions standards.
None of us can stop progress. To me there are a lot of times when progress feels like a step backwards in some ways though.
