2017 vs 2016 W205...major differences?
I also noticed the transmission is quite a bit smoother when going from 2nd to 3rd gear, as well downshifts seem to be less jerky and much less noticeable. One thing I noticed was that the glasses container was plastic in the 2017, whereas on mine it is padded with felt. I guess I got that going for me

Anyone have similar impressions?
After I got my 2015 C300 4M some software update, it shifts way smoother than before.

I would honestly wager that some of the "differences" you felt were imagined, primarily due to simply driving a newer and different vehicle than your own. Otherwise, the only big difference would be due to the vehicle having 18-inch wheels (you mentioned yours has 17-inch wheels). If the loaner had a Sport Package with 18-inch wheels, then it also had a Sport Suspension, which could certainly provide a slightly different road feel than your own C300.
