2013 SV I leased 3/11 has Bose system. Didn't think it would - but as we ordered a particular color SV (vs. having to wait for months for the exact spec SV with QC and LED), it was "take what you get" - no QC and no LED headlights. I was pleased to see the Bose, and it really does have great audio IMO as compared with, say, my 2004 Honda Pilot's factory audio - it is slightly better. Compared with my Dodge Dakota's $700 Kenwood/Fosgate component system (with powered subwoofer) it's not quite as well-defined highs and of course doesn't have the impact of bass - but the truck is so noisy as compared with the Leaf, Ireally prefer the Leaf's Bose sound overall.
Unfortunately I cannot comment on the Leaf's standard audio since I have not tried one out. If I do, I'll update my post. And, yes, I do not like the intrusion of the Bose cabinet into the rear cargo area, but I can live with it since I really do enjoy the sound and I don't ever need to carry much cargo, just a few groceries (that's what the truck is for... how about an EV pickup Nissan??)
