This is a great place for any vehicle service.
This is a great place for any vehicle service. Always call before they start to make repairs and let you know the cost.
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Store of the year
I have never walked into a dealership that had so many enthusiastic people. We were blessed to have Roberto as are sales person who constantly was smiling and making sure we were comfortable. We told Riberto exactly what we were looking for and our price range. He didnt waste our time or his. He got us exactly what we wanted and while we waited for Sam to work his magic Roberto made sure that we were comfortable. Sam came abd introduced himself told us he would get us the best deal possible. Sam did just that. He negotiated for us and got us just what we wanted. Of course we can't leave Will out he got us in abd out of financing as quickly as possible. I want to thank Sam Roberto and Will from the bottom of my heart for making my husband and I feel like family and for making a dream come true for my husband. Keep up the good work I will diffently recommend your store .
Amazing SUV

Great experience with Lucus and the entire closing
Great experience with Lucus and the entire closing team Troy and Joe. This is my 4th Hyundai and Lucus is the best salesman I have worked with. Visited with him 3 different times and he never rushed or pushed me for a decision. Showed me things I didn’t know about my primary car Tucson and now that I just purchased a Santa Cruz too gave me the time showing all of the bells and whistles no one ever took the time to teach me! Now I can use that knowledge with the Tucson too! So much more than I need or could ever remember! I’ve used the service department in the past and had nothing but good experience with them too! So glad I went to Lucus when I had to make a quick purchase!
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Try this SUV before you buy another!
Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.

We just purchased a new vehicle from Hare Chevrolet.
We just purchased a new vehicle from Hare Chevrolet. We worked with Reneau in sales, Ian and Mike from the management team as well as Bryan in finance. All three of them were professional and did their best to help us with our decision while keeping our best interest in mind. They weren’t trying to sell us - they wanted us to get the vehicle that best fit our needs. It didn’t feel like it was a one time purchase, it felt like they wanted to build a lasting relationship with us. Thank you!

A coworker Carmax to me. I enjoyed that you could walk around the lot and actually get inside the vehicles to check them out. No one followed you around the entire time unless you wanted them to. If needed I'd buy and shop here again. The salesman Britt P. was pleasant to work with too. I wanted a better finance rate because my credit score told me I could get one. I was advised to check around. In the end I was able to get a lower rate from another source and get the vehicle I wanted. I'm scheduled for some detail work on the vehicle and I trust it will be done well too.

The mechanics did a terrific job with fixing the issues
The mechanics did a terrific job with fixing the issues of a major oil leak and radiator replacement. Office receptionist Amanda is always so pleasant and friendly. Jason Guerra is absolutely a wonderful Service Agent, seeing to my need of temporary vehicle access, and he keeps me informed about the progress of the repairs on my 2005 Impala.
