2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Awesome car buying experience!
Mr. Wright (salesman) and Ms. Hana (financing), provided awesome customer service. They were NOT pushy or unhelpful. Ms. Hana looked at the apr my bank was charging me, and provided me a MUCH lower apr. They made me feel like a valued customer.
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

I recently purchased a C300.
I recently purchased a C300. When I walked through the door, I received quality service from Arella Berger. Arella was patient with me and did a great job finding a car that matched my personality and needs. Also, I fell in love with their Sales Manager, Allan, who sealed the deal! If you are looking for a dealership with top-notch service and customer-oriented staff, stop by Mercedes Benz in Annapolis. You will not regret it!

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!

The staff I interacted with at Mercedes-Benz of Annapolis
The staff I interacted with at Mercedes-Benz of Annapolis provided excellent service. I found a pre owned SUV on an internet search and called to confirm details of the offering. The used vehicle sales manager, Rori, and my sales agent, Mia, responded to my questions promptly and explained the "out-of-state" buying process in a comprehenisve manner. I agreed to a place a deposit and drove 120 miles to potentially complete the process. The vehicle exceeded my expectations as it was a one owner, fully serviced, and apparently garage kept beauty. The physical dealership was a first class facility and it was easy to view and test drive the ML350. Buying and closing process was efficient with optional coverage presented without pressure to buy. I readily recommend this dealership based upon my buying experience.

Chevrolet SSR pickup....retro truck.
Just bought a Chevrolet SSR retro pick up in the used truck dept. Couldn't be more pleased with this dealership from the sales rep to the manager. After looking for the SSR for at least 2 years, this one definitely was best overall condition and the deal was the best. BTW: they don't jack up the Internet pricing, and do follow up phone calls My rating for them is A

I had a wonderful experience buying my first Mercedes
I had a wonderful experience buying my first Mercedes from Hunt Valley Mercedes. My sales consultant, Veroj, was knowledgeable and professional. He took the time to explain the features of the car but didn't do any typical high-pressure sales pushing. Joe, the sales manager, was fair and respectful during the negotiation process. I can't be happier with the results. I'll definitely recommend Hunt Valley Mercedes to anyone I know who is looking to buy a new car.

My service consultant is DaKari and he is AMAZING!
My service consultant is DaKari and he is AMAZING! I most appreciate his integrity and his honesty. He helps me to understand what my car needs, why and by when. There is never any pressure to get something done - and no dooms day speeches either. Just the facts and a huge amount of consideration for how costly it can be to repair a MB. At my most recent visit in Sept 2025 I had routine maintenance done, but DaKari unexpectedly took additional time to make sure I was receiving the best service from the dealership. I won’t go into details, just know that his CS remains top notch!!! The Catonsville location got a real one!
