I seek an upgrade from my mediocre 2018 Cadillac CT6 Platinum Edition. I am particularly enamored with the aesthetics of the GLE Coupe; however, I am concerned about replacing my commendable Bose Panaray sound system with the base Burmester system featuring Dolby Atmos. Is this an advancement or a regression? This aspect is crucial for me. Additionally, it is peculiar that this coupe does not offer at least an optional superior Burmester system, especially as it is marketed in my country (Kuwait) as a trendy and sophisticated sporty SUV. I am also considering the Cayenne Coupe as an alternative solely because it includes the high-end 3D Burmester sound system. I recognize this may seem superficial, but it is a dealbreaker, as I intend to purchase the best possible overall vehicle of my life.
