Am considering a Tesla Model X to replace our 2015 M-B GL550: https://cars.usnews.com/cars-trucks/mercedes-benz/gl-class/2015 Both are heavy, powerful, luxury SUVs with seating for seven, air suspension, big wheels and tires, but vastly different technology. The M-B has a twin-turbocharged V-8, which is quick and fast, but stinks at startup, rumbles like thunder and burns gas like it was going out of style, which it may be! Replacing it with a Tesla would be a "leap of faith" into vastly different technology, but in a similar vehicle. I'm interested in your experience making a similar leap and what you gained ... and what you lost. Let's start with the sunglass case over the rear view mirror ... the M-B has it ... the Tesla won't, but what substantial differences will I discover?
