It is a nice car but too many problems for this type of car.
Seatbelt restraining system did not work had to replace it
The driver seat heater did not work.
The paint on the driver side and rear door and the rear passenger side door is bubbling from the inside this ca was never in a accident and is a defect from the factory, however Mercedes refuses to repair it,
I am sure this is the last MB I will ever own to may problems for the price tag.
The columb cover between the front and rear doors had to be replaced also.
The cost of this car is not worth the problems I have had with it.
The reviewer repeatedly mentions having many problems, yet they listed very minor wear and tear items on an almost 8 year old car.
If everything you stated were the only type of problems you were having, I'd be very happy in your position. Other people have bought high end sedans and are having to replace very major mechanical/electrical components that directly affect the safety or drivability of their vehicle. You have a solid car, be happy with it.
