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.

Brian and Ayden made my buying experience seamless and enjoyable. They were both professional, knowledgeable, and attentive from start to finish. I appreciated how they took the time to explain everything clearly and made the entire process stress-free. I highly recommend this dealership ? ask for Brian and Ayden!
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.

Best Tesla Deal in Town
Can't be more happier with my purchase. I bought a Tesla from them and traded-in my V8 truck due to gas prices. They shipped the Tesla to me first and picked up my trade. I got such a good deal on the Tesla that if I sell it now I can easily make $5K. The shipping was free and vehicle looks exactly the way it was described. I will recommend Alpha Motorsports 100%. Thanks everyone for making this deal happen.
Great vehicle
This car has everything technology offers in it plus more. The feel of this vehicle is extremely smooth snd quiet. One of the best purchases of ever made. I’m extremely pleased and love it

Elaina our salesperson was wonderful. Responded quickly to all of our phone calls with questions. Organized and completed all the documents so when we drove from MA to MD most of the paperwork was done . The car was exactly as described and ready for us to take home after we signed the documents. Dorit in the finance department was also pleasant to work with. Overall, a great experience with pleasant helpful people guiding us along the way. We love the car and recommend Mercedes Benz of Silver Spring MD. Happy customers!

I had an awesome experience dealing with Mercedes Benz of Tysons Corner. This was the best car purchase experience I have had. The sales person Trivian Anand is such a great customer advocate. The manager, Pascuale, bent over backwards to accomodate me. The finance manager (Sue Kim) was very transparent. Overall it was pure joy to deal with these guys contrary to most other car buying experiences

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.

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!

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

great service
I recently had my car serviced at Jim Coleman Toyota in Bethesda. Like many people I think, I had not taken my car to a dealer for servicing for quite some time. Instead, I used a smaller private mechanic for services like oil changes and the little things that came up, but had not done much in the way of regular maintenance other than that. Earlier this summer we were going to take the car for a long road trip, and I decided to take my car in for an oil change and a check up to be sure it was safe for a long trip. My service representative, Mark Waters did an excellent job. He explained to me what he felt needed to be done. Essentially it was a 60K mile service, All the fluids were checked and replaced, a new drive belt, checked my tires, new wiper blades, and a number of other regular maintenance things. The car drove great on the trip. The trip included many miles on the highway in the pouring rain. I felt comfortable and safe knowing my car had recently been serviced. Upon my return the air conditioning went out. Mark had the mechanic Kevin Parry inspect it and determined I needed a new compressor. They were able to have the car back for me the next morning. Kevin even fixed a few minor body work adjustments on my front fender and on my driver’s seat electrical controls at no charge. Both times I used them, when I picked up my car it was delight to find that it had also been washed for me. I will certainly continue to use Jim Coleman and won’t hesitate to recommend them to others. Five Stars!

Great experiences only!
I've had only great experiences at Mercedes-Benz of Alexandria. I bought a used 2012 GLK from Michael Prati, who was able to find me the perfect match within my price range. He talked me through every step of the way and was always transparent and reasonable. Every time I've returned the service has been helpful and pleasurable! Michael gets back to me with any question I have and is always willing to assist me. Highly recommend.

Ask for the AMG certified, Mike prati
It was a pleasure to be a customer at Mercedes-Benz of Alexandria. I have worked with and bought from different automobile dealerships over 20 years. I informed my sales manager, Mike Prati, who was AMG certified what I wanted from a car. He was the FIRST auto dealership manager who listened when I told him exactly what I wanted my car. Mr. Prati knew more about Mercedes than I could have read in magazines, Car Werk, Edmunds, YouTube etc. He explained the different variables of each model with and pros and cons. He directed me to the E class 450 sedan for a test drive. I personally could not have found the car without his background and experience. I bought the Mercedes pre-owned and certified. What made the dealership a phenomenal experience was how everyone listened and were respectful. Often, customers are talked to which happened at another dealership I walked out of two weeks prior. The goal: sell you something you don’t want. Not at the Mercedes-Benz of Alexandria. Later, I required work on the car. In lieu of calling the Service department I contacted Mike Prati. Who does that? I did. He immediately sent a tow truck, introduced me to a service assistant and I sat back as arrangements were made for a loaner. Mercedes-Benz of Alexandria was organized, cooperative and I had details regarding my car in less than 24 hours. The general manager, which people never see at dealership, called me. He wanted to be sure all departments were working together and I was satisfied. I actually think this dealership off of Pickett Rd in Alexandria has the finest employees. Great attitude. Thorough. Buying a Mercedes? I recommend Mike Prati to sell you one at MB of Alexandria.
