Have the 4x4 version, '16 400.  Cab is the same, here's what I've experienced. 

The Bad--Starter went out the other day. 900+/- hours.  Also had an issue with losing power to the right side console, especially when getting out of the seat.  Think I fixed it by moving some wires around and plugging and unplugging some connectors.  Had a hose rub through on the driveline on the rear of the engine.  It has an oil leak at the bottom of the oil reservoir I can't get completely stopped.  The transmission lock button is agevating when using on a grain cart.  I finally put a 1/4" nut over it and wrapped tape around the shifter to hold it in.  My finger no longer gets sore shifting from a stop, or forward/back now.  Tricky to set the hydraulics if you want them timed until you figure out to cycle all the way through after setting them.  A/C is a little finiky, OEM parts are high, I actually bought the air filters half price at Deere for ours.  Big door that will hit you in the head until you get used to it, only takes a couple wacks.  Stock autotrac is junk, order without and install something else.  We put Trimble in ours.

The Good-- Large cab, Comfy heated/cooled seat.  Excellent sound system.  Good layout for hydraulic control buttons.  Great visibility, Easy to service, cheaper to buy/lease, we leased this one.
