Sorry to see you leave but something to consider; I have had 2 MB vehicles. The first was a 2013 GL350 diesel and the 2nd a 2018 GLC43 AMG. This is the vehicle I traded off to buy my GV70e.
MB vehicles are nice but expensive to repair and maintain. You say the GLE450e is a PHEV. That means you will still have an engine to maintain, plus the electric motor portion. It was my MB experience that the service was good, but they really sock it to you with maintenance costs. On the other hand, the GV70e has 5 years/100K km free maintenance and an 8 year/160K km warranty on the electric motor and related components and the battery. Hard to beat that!
If you only have one vehicle, a PHEV has it's advantages tho. Fortunately we still have a 2nd gasoline vehicle; a 2020
Hyundai Palisade. The vehicle we purchased to replace our first MB, the GL350.
