Hey guys, looking at a 2011 e70, particularly the 35i flavor for the N55 and 8-speed. I'm coming from the E90 world (currently have a 2007 E92 fully bolted) and familiar with the tools and issues for the N54. Looking to have the E70 take over daily commuting duty.

I'll have my Android w/ Carly app handy for any car I look at, but any major issues I should be aware of at first glance?
Transmission or drivetrain concerns?
Sensors?
Water pump or turbo issues?
