1) Vehicle condition - This is a non-smoking vehicle. - Black box included. - This is the last version of M156 I purchased it after confirming the replacement of all chronic disease head bolts and engine parts (if you search for the vehicle number, the replacement history will appear on the Internet). A year ago, while replacing the outer belt, I checked all ABC hoses and replaced one. I hope that someone who knows the value of C216 will choose it. A power bank error appears. I don't think there's really a car with this design that has this kind of output. I hope someone who knows cars will see it. 2) Borrower information - I am using it as a second car. I drive it less than 2,000 km a year and it is not worn well, so I discharge it. I maintain it with Ziktop 0w40 once every 6 months and maintain it by adding 2 bottles of Würth Velbrift each. I maintained it by adding only Mercedes-Benz certified additives to the fuel line. Lastly, only high-quality oil was used. You can clearly feel the difference from a car using regular oil. Fuel economy is 4-5 km/h in the city and 8-10 km/h on the highway. Fuel economy seems to be better at high speeds above 130.
