About the Mercedes-Benz GLK350

Vehicle Summary

A luxury compact crossover SUV like one from the Mercedes-Benz GLK-Class can be a great option if you want to enjoy elegant cabin features without sacrificing space or utility. The Mercedes-Benz GLK-Class of crossover SUVs was produced from 2010 through 2015 before being rebranded as the GLC class for 2016. 

The GLK350 is a well-appointed trim option on the GLK-Class, offering seating for five passengers across two rows; and when needed, second-row seats can be folded to extend cargo storage to a full 54.7 cubic feet on the 2015 model as well. Every GLK350 is also outfitted with a 3.5L V6 engine and seven-speed automatic transmission. Meanwhile, Mercedes' 4MATIC all-wheel drive system is also available if you want to tackle tougher terrain with confidence.

Overall Rating

4.6 out of 5 (25 reviews)

Ok...if you dont mind crazy gas prices

Yes and no, this car is an excellent deal for the engine and life of the vehicle. However this car EATS gas like crazy!!! I do not think I am getting 16 miles to the gallon. I think its way less. Also its expensive to keep up! But hey that is the cost of luxury vehicles. The model I purchased was a base model with 25000 miles. Excellent deal cost wise.


  • Ride and Handling: Wonderful to drive
  • Power: fast car
  • Braking: fast and smooth


  • Fuel Economy: Worst ever!! Less than 16 miles to the gallon
  • Cost to Maintain: Very expensive
  • Technology and Entertainment: Mercedes is way behind when it comes to technology

- Sonja Thomas, 2010 Mercedes-Benz GLK350


I love this car. I upgraded from an SUV that I had for 15 years and it was on it's last leg so I am sure that has made my opinion a little biased. I love the parking assist and backup camera. It takes the guess work out of parking and saves your bumpers from scratches and dings! I love that the hatch opens and closes via a button instead of having to open it yourself. Sounds lazy, but when your hands are full and you are approaching the tailgate it is nice not to have to put stuff down to open the hatch.


  • Technology and Entertainment: Makes everything more convenient!


  • Cost to Maintain: I know service visits will be costly, uses only premium gasoline, and replacement tires are expensive.

Perfect for a mommy

Purchased this vehicle 8 months pregnant. It's perfect for me to drive around my little one. Fits stroller comfortably in back. I didn't want a car that was too big, but that made sense for a growing family and this is it. My husband has a Range Rover évoque and I find this one a smoother ride and much easier to drive. Only con is that there are no seat warmers which I feel should be standard in a Mercedes. The technology is a bit dated but works great and easy to use.
