The sales people I worked with were great and very patient as I made my decision about which car i was going to purchase (between Acura and another make). They never rushed me and were always very helpful. When I finally made my decision to purchase a 2016 Acura MDX - advanced package, it was a Friday and the process was just bad. First, we waited about 20 minutes for the finance person, which wasn't that big of a deal but i was surprised they only had 1 person working. When we finally got done with the finance person, the salesperson took me out to take a look at the car i had just purchased. Well, there were very noticeable scratches on the rear driver side of the car. The manager came out to look and said they could buff it out for me. Considering I just wrote a check for half the value of this car, i wanted them to find me a new one. I did not want one with a "defect" that they would just buff out. They didn't have another one in the dealership and had to bring one in. I could definitely tell that the manager was trying to dissuade me from bringing a car in from another dealership but i didn't care. In the end, they sent me home with a different MDX that had all these stickers and other advertisements for their dealership. The next day, they called me in to notify me that they had found me a new car. I went to the dealership to inspect it and everything looked good but it was quite dirty is some spots. They took the new car back to have it cleaned but also to put on some protective coating that i had got. When the car came back (maybe 1.5-2 hours later), it was still dirty and i again pointed out the dirty areas. The sales person took it back to be cleaned again and when they brought it out, IT WAS STILL DIRTY. At this point, i am super angry and annoyed. The parts that were dirty were not obscure parts of the car. I mean, the people cleaning the cars must be working in the dark. Maybe Chevy Chase Acura needs to invest in better lighting. They cleaned one side of the dirty part but not the other. At this point I was quite vocal (to my husband) in my displeasure and regret in not tearing up the check the night before and going with the other car. The manager never came over to explain anything to me about why it was taking so long and why his staff were completely inept. The salesperson mentioned that some manager was going down to the service area to see what was going on. When the manager (maybe GM) walked by during one of my rants to my husband, he gave us two Acura water bottles. Which, i guess was a nice gesture but didn't make up for the very long and unnecessary process. When the car was eventually done and inspected, i just wanted to get the xxxx out of Chevy Chase Acura. The salesperson explained the features of the car to me and we were off. Well, after driving a few miles down the road on Wisconsin Avenue, my husband turns to me and says "make a u-turn and go back to Acura". He wouldn't tell me why but just told me to turn around. It turns out that the piece of plastic above my rear-view mirror WAS MISSING. We went back to the dealership and the manager took a piece from another car and put it into mine. No real explanation or apologies were given. Again, the sales people were very nice, professional and patient with me as I made a decision on which car to purchase which is why i gave this review 1 star. Honestly, the car itself is fine. It drives well and is nice but I can honestly say that I would never purchase another car from Chevy Chase Acura. I've purchased/assisted in the purchase of cars from Herson's Honda, BMW of Rockville and Euromotors in Bethesda and this was by far, the worst experience ever. I would definitely NOT recommend this dealership and I haven't.
