I am coming out of a 2015 S550 Coupe, and this 2020 S63 AMG absolutely has blown my mind! It is everything I wanted in an automobile. Luxurious, yet refined!!!!

Although I’ve never written a car review before, I feel it’s important to share my experience with this vehicle. Since I purchased it, I’ve encountered a series of problems, starting with a fuel pump failure that stranded me on the highway. The electrical panel malfunctioned three times, and I faced alignment issues—one was a recall, while the other was due to improper alignment. That was an ordeal itself. I was left waiting over two hours on two occasions for Mercedes to tow the car to the dealership. So much for Elite car services. Despite bringing the car in multiple times to request an inspection of the brake pads, mine you the car had less than 15,000 miles on it.I was incorrectly told that they didn’t need replacement. Eventually, I consulted an independent mechanic, who confirmed they needed to be replaced and that I had been driving on worn rotors. Overall, in just a year and a half, the car has been in for repairs seven times for a number of reasons. I have had to rely on loaner vehicles five times, each for over a week, only to find the repairs were still incomplete. In my 30 years of driving, I’ve never faced such a nightmare with a car. It’s such a shame because the car is beautiful!! Regrettably, I had no choice but to trade it in for a different vehicle, and it’s not a Mercedes!
