Yes the E70/E71 problems are well documented. Problem is that everything is electrical, and everything has a sensor or module on the 07-up models, so DIY or just a quick diagnostis with DIS is out the door on those models.

I wouldn't purchase something I'm not easily able to DIY or work on/diagnose myself. Unfortunately, making these cars complex over the years has also contributed to them not being as easy to work on at all.
