Daniele Bava was extremely friendly and helpful
Daniele Bava was extremely friendly and helpful throughout the entire process. He took the time to clearly explain everything, answered all of my questions, and gave me different options so I could make the best decision. I never felt pressured, and he made the experience smooth and stress-free. Thanks to him, I was able to leave with my new car the same day! I highly recommend working with Daniele.
Most reliable and usefull car I've had as a daily driver.
Most reliable and usefull car I've had as a daily driver. Everything in the interior is placed where it should be found functionally. Power, while not a muscle car, is more than adequate. Gas mileage is excellent. Adjusting from Comfort to Sport make a very noticeable impact on the driving experience from gear shifting to steering...

Brian K, Daniel I, and Mohammed A did a great job getting
Brian K, Daniel I, and Mohammed A did a great job getting me in and out in about 2 hours with my new Bronco. On a Sunday afternoon, no less! Even staying past closing time and filling up the gas tank so I could enjoy my first joy ride once the paperwork was signed. I'd been putting off buying a new car for years because the stress I imagined came with the process. But they made sure it was streamlined. Before arriving at the dealership, Daniel informed me in detail of all the new year's incentives I was entitled to ($4000), in essence making this an offer I couldn't and shouldn't refuse. Thanks, guys! Great team work.

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.

Bought an amazing hybrid car with low mileage and a very competitive price from Motorcars of Gaithersburg. I had a great experience there. Ishmael's team was exceedingly professional and courteous. I walked around the showroom to see what else they have for sale, and saw a ton of solid cars in great condition. Would purchase a car from them again no questions asked.
There are 20 matching cars close to your year range.
