That said, my 2015 has about 56K miles on it now, and still feels new when I vacuum and wash it. What about yours "does not feel new"? Now, I will admit, I did not get my CX-5 new, but owned a new 370Z and new C6 Z06, so I know what "new" feels like in a vehicle.
My CX-5 still shifts snappily, does not rattle, etc. and to me, that is "new". No appreciable interior wear.
I will have to keep an eye on my engine oil levels, and may send some off for analysis this next oil change (dealer used their oil, I prefer a different oil, so I'll wait and do the UOA on MY oil, since the dealer thing was a mistake and likely won't happen again, so the numbers won't mean much).
