W220 is available in different versions. You must choose the engine type used, production date (facelift/prefacelift, [[D2B]] vs [[MOST]]) and wide range of [[Data Card|optional equipment]].

== Inspection checklist ==

=== Questions to the seller ===
* Ask in what condition the car is.
* Ask what defects the car has. If the seller claims that he is selling car in a perfect condition, any issues found by you can be a good bargaining reason.
* Ask what significant repairs the car has passed recently.
* In which workshop the maintenance work has been carried out.
* Ask how long the owner is owning the car.
* Ask why the owner is selling the car.

=== Technical inspection ===
* As the first thing connect [[STAR Diagnosis System (SDS) or Diagnosis Assistance System (DAS)|DAS]] and run quick test. Print the error codes to PDF and clear them. Rerun the test after other inspections and driving tests are performed. See which error codes reappear.
* Enter "AAC - Automatic air conditioning" section in DAS to perform quick self-test (will check if all flaps and actuators work).
* Check the wear of leather on seats and steering wheel.
* Check what [[Wheels, Tyres|wheels and tyres]] are installed. Check if it complies with W220 specification. Check tire wear.
* Inspect chassis for rust. Ask if any anti-rust spray has been used.
* Check windows from inside. Look carefully for any cracks.
* Check if windshield spray works correctly and windshield wipers work.
* Open the hood. Check if hood mechanism works correctly.
* Check if handbrakes work. Can they be released easily.
* Press the [[Airmatic]] level control switch and see if the car rises.
* Check if headlights function properly. See if automatic level adjustment works correctly on startup.
* When starting the car use [[WIS 15.40 Generator / Alternator|built-in voltmeter]] to see if alternator is functioning properly. Try to gas the car - the voltage should not fluctuate, but stay fixed around 14V.
* Take the car to dark place and see if interior lighting is working. Check specifically if the door handle illumination for all doors work.
* Check if all functions for all seats work.
* Check if window controls on all doors work.
* Check if turn signals on exterior mirrors work.
* Check if exterior mirror controls work.
* Check if exterior mirrors fold in and turn signals still work.
* Check labels on windshield and all windows. For original windows year number should be the same or older as the production year.
* Check COMAND and its functions.
* Check if Parktronic system is not switched off and all sensors work.
* Check if in the [[Tail Lights|tail lights]] all bulbs work and no LED bulbs from the break light module are burned out.
* Check the label on the [[Tail Lights|tail lights]]. Are they original (have MB logo) or are DEPO aftermarket tail lights.
* Check the installment of [[Tail Lights|tail lights]] - if they do not blend in smoothly the car might have been deformed in an accident.
* Check if there is SXXX logo on the trunk cover - if not the car has been repainted.
* Check the type of exhaust pipe and how well it is installed (originally, unless W220 has AMG package, the exhaust pipe should not be visible).

* Check if the trunk can be opened by smart key and by pressing the button.
* Check if the trunk and doors can be unlocked mechanically using metallic key.

* Make turns and look for clunking sound.
* Accelerate and see how swiftly the automatic gear shifter works.
* Accelerate very fast and suddenly release the gas pedal. The car should not convulse.
