 Bought a 2017 e300 with P3 package, complaint. It is awful. It's been in the shop 4 times. Transmission issues, back up camera problems, climate control, HD radio does not work. Doors had to be slammed shut. Home Link did not work. There is still not a fix for the HD radio. It was in the shop for 2 weeks, with no resolve. It is back in the shop now for rear view camera intermittently working, climate control turning off and again to look at the HD radio. The transmission was fixed, and the body shop reset the doors on the third try. I've asked the dealer to buy it back and they won't.12/2016.  Mercedes finally agreed to buy back the car due to its inherent suspension problem.  Strangely the service records say no problem found.
