I never had a Merc. I test drove a few, never cared for any of them. The brand never spoke to me either. All that said, after driving the EQS, I might consider the EQS AMG version, especially if they can build me one before Porsche can build me a Taycan CT Turbo (I've been waiting for an allocation since this summer). The EQS actually looks better in person than in pictures, though definitely bland, but I think I can live with that, especially that flashy looks that stand out are not high on my priorities list (one reason I liked the Model S, understated but elegant, I even deleted the red calipers from my P85D because I don't like them on a while car). This is the one I drove (I think, there was 5 or 6 of them there). It seriously felt like a luxury Model S with more modern tech inside:
PS> I hate the charge port on the passenger rear side. Copied from ICE car fuel cap without considering the EV driver experience of charging at home as opposed to the gas station or public charger (e.g. plugging in every day in a garage, why have to walk all the way around to plug/unplug every time, even worse if the car is parked with passenger side to the wall).
