Amazing experience.
Amazing experience. Bazil was fantastic, got me into the car I wanted at a great price and I will be back for more in the future!
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

I enjoyed my test drive experience and the staff was
I enjoyed my test drive experience and the staff was attentive. However, the rep who worked with me and my boyfriend insisted on accompanying us on the test drive. No other rep had joined us at other lots, either private or dealership, so it seemed like more pressure and less privacy. We also had to tell the dealer that we’d meet him inside after talking privately. Again, pressure. That, plus no acknowledgement of the need for cosmetic repairs—duct tape under the seat, a hole worn through the driver’s car mat—made it fairly easy to walk away from a decent car.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Had a great experience working with salesman Jonathan
Had a great experience working with salesman Jonathan Molina and the finance team. Koons offered the best price and made sure I received a competitive rate. They also didn’t add in any ridiculous fees (I explicitly said no maintenance package at the beginning and they respected that).
Great car!
Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

Excellent dealership!
Excellent dealership! The price you see on their advert page is the price you pay. That's so rare now since covid. Excellent salesman and Excellent finance department.
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

The proficiency, expertise and professionalism of Euro
The proficiency, expertise and professionalism of Euro Motorcars Bethesda is second to none. My review would be meaningless if I didn’t give very special acclaim to the key associate who contributed great to my extraordinary experience. BRADY INFIELD is one of your greatest assets. He exhibits the professionalism, courtesy, patience, energy, enthusiasm , character, empathy, intellectual curiosity, self control, and self esteem that any organization would need to to advance their agenda! After all, you sell classy cars so you should have class, such as Brady Infield, to embellish your mission. It’s small wonder Brady Infield is a rising star with an enormously bright future; he’s under the tutelage and support of Tyler Griffin. Thank you Tyler Griffin and Brady Infield!

As always, the dealership does top quality work and I am
As always, the dealership does top quality work and I am very pleased with the job they did for my 2021 S585 sedan. I was especially impressed by the video of the proposed repairs and maintenance work - a new service that worked out very well. One aspect of this visit however could stand to be improved. It took 2.5 days to return my car to me, largely due to the unavailability of a check out driver to validate that the car was ready to go - at least that's what I was told.
