I had Q7 2.0 as a loaner car and have test driven the bigger engine too a few years ago . My feelings are similar to yours though I find the mmi very good but that is probably also because we have had a bunch of Audi’s lately and I am very used to them though I do like that our bimmers have the wireless Apple car play.
With that said it is on our short list as a replacement for the MDX which is gone this October which btw creates another problem but I think I already hi-jacked this thread enough
