Cadence 2021

Hello and blessings from God and His mercy and peace. Dear brothers, I would like to inquire about the 2021 Cadenza from all aspects: fuel consumption, sound insulation, and comfort, focusing on the full trim. Also, what is the difference between the 3.5 and 3.0 in terms of torque and fuel efficiency? What worries me is that it has only one design, and they changed it in 2022. I kindly request comments only from brothers who actually own the car. Thank you.
