It is very reliable and safe. It is made extremely well.
I only buy Mercedes but that is because I work for them. Either way, I do love them. The cars do get nicer as the class increases. I have leased these cars in a few different classes. The M and E class are much nicer than the G class.

Qualities of a good vehicle.
My vehicle is a convenient mode of transportation. It has comfortable seat, ventilation and other novel technology. It is very easy to drive. I couldn't see any problem. I can say it is almost perfect and excellent. Their dealership is very friendly. They want to give more opportunity as their possible.

This car will definitely turn heads and people wish that your car was theirs.
My car runs great. The engine is not loud and annoying. The interior almost beats the exterior of the car. My Mercedes is black and shines beautifully. The gas does not run out quickly and only need about 35$ for a fill up. She runs very smooth and easily like she’s floating. I never have trouble with this car. The Mercedes is an awesome car to buy.

Really comfortable car, I enjoy driving it and trust it. Lot.
It is really comfortable to be in, and also super safe. It is a great family car and I trust having kids in it. If you are having a bad day, if even has a massage feature you can use! Sometimes a message will go off (ex: tire pressure) and when I want to fix it they tell me everything is fine, so I assume the sensor has something wrong with it, but it happens all the time which can be frustrating.

Luxury is a big plus. Gas mileage could be better.
Very powerful vehicle. It's not very fuel efficient, but great performing and very fast. The vehicle is very comfortable and luxurious.

2018 Mercedes is amazing!! I love it so much!
Amazing! I will keep this car forever. The only thing I hate is that there is only ONE cut holder! I bought this car last year and it will for sure be the last car I buy. Everything about it is right up my ally, it is the best. I feel great when I driving it and I love that!

Great car, minor issues with windshield wiper and key fob.
Windshield wiper is streaky shortly after replacing. Battery in key fob died within first 6 months. No other issues with the car. Has been reliable, luxurious, drives well. Would buy it again if needed a new car. Have driven some competitors and prefer this.

This truck attracts a lot of unwanted attention from law enforcement.
The ride isn't as smooth as you would like but everything else is great. I purchased this vehicle because of the flooding in Houston and it hasn't let me down. All of my friend and family like this vehicle. I don't think I will ever trade this truck in or sell it. The body style has been pretty much the same forever.
