Whilst I just took delivery of EQC, changes were made by MB to my spec i.e. I ordered it in MY21 but they made modifications to the order using MY21.5. They didn’t make all the changes based on MY21.5 but only certain ones. I had downloaded the MY21 brochure before the MY21.5 brochure was released and did a specification comparison between both brochures for the differences which were the removal of the Burmester sound system, wireless charging tray, AR sat nav and change in wheels. Perhaps you can try that a brochure comparison?
