I ordered this car with all available options. Towing my horses on highways and hills is effortless and I have NEVER gotten less than 20mpg. I find the nav system very accurate but data entry is a pain. The Airmatic suspension makes a HUGE difference in the ride and handling quality over lesser-equipped M Class cars. There have been zero defects, so my only expense has been to replace the tires and 3 maintenance stops. An outstanding vehicle made in the USA!
