The new S580 is without a doubt one the finest sedans in the world. The technology is awesome and the handling is beyond anything I ever imagined. I've had more compliments on this car than any other car I have ever owned and I have owned a lot of cars.

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!

I have owned this vehicle for 4 months. I looked at cars for about 6 mos before I bought it, for the last 10 years my daily driver has been an 11 MB E-Class from which has given me great service, almost 300K miles on it. The S-Class is very nice, its Black and gets attention everywhere it goes and I mean everywhere. It has lots of tech, the ambient lights, seats are comfortable. The car is very quick but you have to make it go very quick, it prefers to be a cruiser. I've taken it on a couple road trips and you arrive at your destination feeling fresh, little or no fatigue. I normally drive the car in the comfort mode but occasionally find myself switching to sport mode, sometimes the floaty feel aint what i'm feelin. There are so many great things to say about the car but here are couple small problems with it, 1st as mentioned earlier, everthing is done via the tablets, for instance, you can adjust seat comfort a million ways but you do it on the tablet, kinda completed, sometimes when you change a setting it changes a setting you'd already set, for instance, I took the car out of town last week and before I left I had the car set to fold the mirrors when I exit the vehicle, somehow it stopped working so last night I changed it back, but when I got out the car the illuminated MB star that normally shines on the ground when I open the door wasn't there, so I had to go back to setting and turned the locator off then back on and I changed setting to fold mirror to off then back on and it started working again, quirky stuff. I've also experienced when I crank the car using the app on my phone, sometimes when I get to the car there is a strong gasoline smell in the car, it never happens when I use the push to start. I also own a CLS 550, a Porsche Boxter, an E Class and 330 BMW Vert, wife drives a 19 X5, now the X5 is sweet also, very comfy and fast. While the S is fast but you have to make it go fast with the X5 you have to make it slow down as it pulls hard.
