This is my 3rd 5 series. Major factor in my decision making was a simple fact that BMW leases are just unbeatable. Similarly configured Benz or Audi would be somewhere around $300 more a month. I did cross-shop among the 3 Germans over the last 10 years.
Where is BMW going with the 5 series? I looked in my crystal ball and I see the 5 is here to stay, just like the A6 and the E-Class. The car will be highly electrified (like the rumored next M5), if not offered in a fully electric flavor. Electrification will be the answer to the straight line performance question which now a base Tesla model 3 can challenge (540xi). Now that BMW does over the air updates, options as subscription services will likely kick in soon as well (which I like).
On the topic of LCI, I think Benz did a better job with the LCI mainly by NOT removing options but by adding refreshed items. However, if we don't compare against Benz and if we forgive the missing option(s), the G30 LCI seems to be bringing more pronounced changes than the F10 LCI back in 2015 (significantly refreshed lights, much bigger LCD screen, the electric motor for 540, etc). Overall I think they did a decent job with the LCI. I wish BMW added more aggressive hood sculpting mimicking F10, granted hood cosmetics don't typically come via LCI. F10 was and still is such a beautiful sedan. Much greater road presence over G30. Couldn't resist, had to compliment the F10 again....
