We could not be happier with our experience and purchase!
We could not be happier with our experience and purchase! Our salesperson, Vince, was helpful, knowledgeable and went above and beyond to ensure we were happy with our purchase. We came all the way from Gwinnett, and are so glad we did! If you want a dealership that treats you with respect, is efficient and doesn't play games- this is where you need to look. I highly recommend you talk to Vince, especially if you are looking for a pre-owned Audi.

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.

First time shopping at EchoPark.
First time shopping at EchoPark. I had driven by the location a thousand times and then I purchased a vehicle there. It was an easy and zero pressure process. The price was lower than KBB value. Didn?t get stuck in an office with a pushy sales manager trying to sell me an extended warranty like most other dealers. I highly recommend EchoPark in Duluth. Antoine was very friendly and helpful.
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.

Had a fantastic experience buying a plug-in hybrid from RBM of Atlanta. Jason Friedman was knowledgeable, patient, and made the whole process seamless. Since the car was a gift for my daughter’s 16th birthday, Jason even surprised us by putting a big bow on it — such a thoughtful touch! Highly recommend both RBM and Jason

Was provided good service with them.
Was provided good service with them. I went to check out a Nissan Sentra for my daughter but came out with 2020 Kia Soul which was better/ comfortable car. Smooth finance team and process. My only advice is if you buy a Kia make sure you know if your current insurance will cover the car and look at the cost. That was my mistake (it was on a Sunday) because I was told things were good with insurance company's covering Kia. I was going to return the Kia and get something else because they don't have a return policy. But, my daughter loves the car but will trade it in about 5 months and get something else from Atlanta Used Cars.
