 First, I will say this car looks pretty nice, and handles well, but that's about it.  The seats are hard as rocks, and extremely uncomfortable on a long trips, regardless of the adjustments. The floorboard appears to go down at an angle, so I couldn't even get my feet in a comfortable driving position. Access is very poor, with the seating very low, and with trying to wedge between the steering wheel and the B-Pillar. The controls are horrible.  Instead of knobs, there are very small levers for everything, and they are all the same size.  Why would a "sync" button be the same size as the blower control?!  I set my favorite radio stations, but haven't figured out how to get back to my list of favorites for the last 6 months.  When I try to change stations, it seems to jump back and forth between satellite radio and FM. The "advanced electronics" try to tell me to rest when I am not tired, and beep at me when there is nothing in the road. At 6,000 miles, I was left stranded when my serpentine belt jumped off, and the car overheated.  I found out that run-flat tires can't be repaired, so a nail cost me $420 for a new tire at the dealership. I had a 2014.5 Toyota Camry prior to this, for 38,000 miles before my wife totalled it, and would gladly take another.  It was inexpensive, comfortable, easy to operate, and it NEVER needed repairs.  Not to mention it was much roomier.  I will be very happy to end my lease of this C-Class.
