The material used in the car seats is not genuine leather, but rather bonded leather. Excessive pressure on the armrest can cause damage to it. Personally, I always place a microfiber towel on the armrest of my cars to protect it. For instance, during the summer, I always have sunscreen on, and my leather seats, which are almost white in colour, are prone to damage. I also experienced this issue in my 640d car, which had red vermillion rot leather seats. The dashboard, although made of leather, is also bonded and not of the same quality as the seats, which are made of analine nappa leather.My M4 is an upgrade and is made of merino, which closely resembles genuine leather.Furthermore, your chairs seem to be securely attached on the sides, using high-quality Dakota leather.That is to say, it is neither genuine or authentic.
