I recently purchased my BMW XM from Kia of Riverdale, and
I recently purchased my BMW XM from Kia of Riverdale, and I couldn’t be happier with the experience. From the moment I walked in, the customer service was top-notch, and I want to give a special shoutout to Pete O’Brien. Pete was not only incredibly professional and knowledgeable but also funny, engaging, and truly a joy to work with. He made the entire buying process smooth and stress-free, and his personality kept things light and enjoyable. I also traded in my previous car, and Pete went above and beyond to make sure I got the best possible deal. He’s the kind of person who genuinely looks out for his customers and ensures you leave with a great car and an even better deal. If you're in the market for a vehicle — especially if you’re looking to trade in — I highly recommend going to Kia of Riverdale and asking for Pete. Outstanding service, a great deal, and a memorable experience. Thank you, Pete, for making my BMW XM purchase such a positive one!

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.

I purchased a BMW from Cartopia.
I purchased a BMW from Cartopia. Adam worked with me. He went above and beyond to accommodate me during this process. There aren't enough kind words to describe the service level I received from him. I will definitely recommend anyone looking to purchase a vehicle to go to Cartopia .
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.

Amazing!
Alexandra Maydelman is an exceptional businesswoman. We had a little check engine light issue, and she spent a fair amount of time and effort in getting it fixed. She gave me her word on the final repair, and sent me the check she promised, on a "hand shake". That is the kind of behavior that restores one's faith in honesty and integrity in business. "A" plus!

Acura MDX 2017
I recently had the pleasure of working with the salesman Chris Kang who helped me close a deal on 2017 Acura MDX. He was great to work with throughout the process. The management also worked with me to get a best possible deal. Overall very happy with the purchase. I especially recommend Chris Kang because he will do his best to get you what you need.

Great Tech Service
I recommend anyone needing service for their Mercedes Benz, choose service tech Buddy Lim. Definitely a step above the rest, if I could leave a cash tip, I would. Straight forward and honest. In fact when I upgrade my car, I'm going to ask Buddy which salesman to use, if he trust him, so can I.
There are 20 matching cars close to your year range.
