I rarely leave reviews, but after two visits to this dealership, I feel it's important to share my experience. My first visit was on July 15, 2026 to look at a 2022 Mercedes-AMG CLA 35 that had alrea dealership, I feel it's important to share my experience. My first visit was on July 15, 2026 to look at a 2022 Mercedes-AMG CLA 35 that had already been listed for sale on the dealership's website for over a month. To my surprise, the vehicle wasn't even ready to be shown. The wheels had been removed because they were being repaired, the front bumper was heavily scuffed, the "T" was missing from the Turbo badge, and the car couldn't even be test driven. I left expecting the vehicle would be properly reconditioned soon. I returned on July 26, 2026, nearly two weeks later, expecting the vehicle to finally be ready. It still wasn't. Despite that, there was continued pressure to leave a deposit on a vehicle I had never been able to drive. Unfortunately, the sales experience became even worse. During the appraisal of my trade, the salesperson Daymond asked, "What are you looking to do?" I replied that I was "trying to get a better deal." He immediately stopped and questioned my response in a way that made me feel like I had said something wrong. I actually asked him, "Was that the wrong thing to say?" and he responded, "Yeah." When I explained that comparable vehicles with more miles and fewer options were selling for more money elsewhere and asked if he could take a look, his response was, "That's not my job. My job is to sell the cars that are here." The conversation became unnecessarily confrontational when he then asked me, "Did you come here to argue with me?" At that point, I requested to continue the process with the sales manager instead. The sales manager was professional. Unfortunately, the finance process created another issue when my credit application was submitted with incorrect employment information, including the wrong length of employment and incorrect previous employer. Those errors affected the financing process and should never happen when someone is making such a significant financial decision. Another thing that stood out was the repeated emphasis on "market value" when discussing my trade-in, while there seemed to be little acknowledgment that the dealership prices its own inventory aggressively as well. Every additional $1,000 they considered adding to my trade allowance up to about $2,000 was presented as though they were doing me a personal favor rather than simply negotiating a fair deal. I understand every dealership needs to make a profit, and I respect that. What I don't respect is advertising vehicles that aren't ready to be shown, encouraging customers to leave deposits on cars they haven't been able to test drive, confrontational communication, and inaccurate handling of a customer's financial information. I expected a much higher level of professionalism from a Mercedes-Benz dealership. More
Service Dept is a total ripoff. For a car one year old and 1733 miles on it with nothing wrong gets a total bill of $800.49 for just a checkup is outrageous. I kept getting this mes For a car one year old and 1733 miles on it with nothing wrong gets a total bill of $800.49 for just a checkup is outrageous. I kept getting this message on the dashboard of service required. Went to service just to have that message removed from coming up and nothing else wrong. I believe the advisor should told me if there is nothing wrong and the car has such low mileage we will just remove the message and that's it. Instead I get a bill for $800.49 for work that was not needed. This is my first visit to this Service Dept and will be my last. If I was told the bill would be this high I would turned around and gone home. Having a Mercedes is not a license for outrageous necessary charges. I never give negative reviews but this one deserves it and to top it off I waited in the waiting area for 4 hours. More
I met Dawn, my service advisor, for the first time when I brought my Mercedes GLA 250 in last Wednesday and Thursday. I was not fond of my last experience there back in 2/2024, so I had not returned until n brought my Mercedes GLA 250 in last Wednesday and Thursday. I was not fond of my last experience there back in 2/2024, so I had not returned until now. Dawn changed that. She sent a service video showing exactly what needed to be done. We discussed the services and costs, and she gave me time to think about it - no pressure. Last week I had four new tires and an alignment done. The dealership provided transportation home Wednesday and picked me up Thursday. My car was washed when I got it back. I received several calls, texts, and emails keeping me updated. Clear communication, fair pricing, and respect for my time. Dawn's expertise is evident. Prov 22:1 "A good name is rather to be chosen than great riches." Thank you, Angela Genecki More

Our recent travels to Union Mercedes-Benz was clearly to work with Lenny again. We are repeat customers. We passed two MB showrooms on the way.
