Hello. My name is Cristian. I collected my Mercedes S Class 350 D Line Premium 2019 on 04/06/2021. So one week ago.The place where I bought the car is 270 miles away. After about 200 miles when I coming back with my Mercedes , I heard a strange noise from the front, left. The plastic cover was detached from the screws and had contact with the road ( Just I think was detached from the screw because first aprox 200 miles no any problmes ) I managed to put it back with my hand. But before arrived home hapend again. I didn't have much trouble with a minor thing I want just fixed myself without any complain..Since April 6, 2021, when I got home, I have only used the car twice. The proof is the mileage. The car run only 313 miles. But booth times I had problems with the plastic cover, front, left. But today, when I lifted the car on the elevator, to an authorized mechanic, to fix the plastic cover, I was amazed to find that all the plastic cover in the middle of the car is missing. I don't know what happened. I didn't have the plastic cover when I left Carliste by car or this plastic cover got lost on the way because was detached from the screw . Mercedes Benz have to find. I contacted the car salesman, from where I bought the car. He told me that the car was prepared at Mercedes Benz and I received a phone number. I contacted them and made an appointment next week. But it is complicated because this Mercedes Benz is not in the city where I live and I will lose a lot of time after I paid 40,000 pounds. I don't understand how the car could leave Mercedes Benz with such a problem. Mercedes Benz is synonymous with quality at a very high level. But in my case, unfortunately not. I did not provide any details, but if Mercedes Benz contacts me I can provide my full name, car number, address, seller name, Mercedes garage name .................... Thank you.
