I really enjoyed the buying process.
I really enjoyed the buying process. Michael was great. Honestly, it sucks to buy a new car. No way to sugar coat that. It?s a long process, but my salesman was young and sharp. (He kept bringing me water, and I kept drinking it. :). Overall great place with great folks!
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.

Getting a car at Autonation Katy was a breeze.
Getting a car at Autonation Katy was a breeze. Justin Hernandez actually introduced a better car for better value than the one we were originally looking at, was very knowledgeable and answered every question patiently. Great guy to work with!
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.

Ozzie and Belinda took great care of us.
Ozzie and Belinda took great care of us. 1. We had to trade in a car that was costing too much to repair. I put the information into the Echo Park system and Belinda called to ask further questions. It was that outreach that had us going to Echo Park instead of CarMax. 2. Ozzie was the salesperson who happened to be free when we walked in. He listened to what we wanted to do and made a couple of good suggestions. Then one test drive and we were ready to buy. The dealership honored the trade-in value and even added $250 to it, and altogether that helped pay for the warranty that we purchased.

This has been the second best experience on buying a new car from Alex Wier. He took his time and was so very patient with us. I will continue to buy my next Toyota vehicle from Joe Myers Toyota. Usually it feels creepy walking into a dealership, but this place was very comfortable.

Very good experience.
Very good experience. “H” Humberto was really good to work with. I would highly recommend I lay down and R&T Expo!! We were an out-of-state purchase and had to fly in. H worked with us and made us very comfortable. Took a video for 30 minutes to show me the inside and outside. Something that was very important purchase google carr.com reviews. I’m not sure about some of the bad reviews but we had a wonderful experience. When we flew in and got to the car dealership, H told us he did not want us to buy this vehicle without feeling absolutely comfortable. Allowed us to test drive it huge answered all of our questions. Thank you H and R&T Expo!!
