Round Rock Hyundai provided me with an exceptional experience in purchasing a new 2025 Palisade. The salesperson Victor awaited my arrival and had all the procedures in place to insure I was satisfied with the experience. Victor Lao walked me through all the features/functions of my Palicade.

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.

AWESOME!!
As soon as I walked in the salesmen was there to greet me and help me right away. i live 4 hours away from this dealership and they were great working with me long distance. Their prices are reasonable and good to work with, I just recently purchased a jeep with them which had a few problems and they automatically wanted to fix them before giving it to me which was great. Love them so you should too.
GLC43AMG

Erica was a pleasure to work with.
Erica was a pleasure to work with. She quickly assisted in getting my deal put together and she was professional, helpful and straight with me. She jas since followed up to make sure I am happy. I highly recommend. her assistance in purchasing a new Mercedes!
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.

I went to this dealer to take a yearly service.
I went to this dealer to take a yearly service. While I was waiting, I wanted to get a trade in value for my 2020 Benz GLC 300. I met Erica at sales. She was exceptionally good and knowledgeable. She showed 2 or 3 models and gave me good price. I traded old one to new 2025 GLC. When I drove the new car, I found out new model did not have the option of distronics option that I needed. When I called her back, she did her best to find the car that has that option. I went back to change to another 2025GLC with more options. She did lots of extra work to get this done. I really appreciate her work. If any one who is interested to buy the Mercedes Benz, I strongly suggest to see Erica at sales. Thank you Erica.

Mrs.Erica was a tremendous help throughout this
Mrs.Erica was a tremendous help throughout this custom-order car-buying process. Midway through, we had to switch sales associates. While we also did not know the unknown impacts of the tariff effects being placed, in the end, it worked in our favor. She is truly an outstanding individual and a high-rated worker who is rising in the car industry. We are enjoying our new beauty! Thank you again!
