Sapaugh GM Country review
As a woman who honestly knows nothing about cars, I was
As a woman who honestly knows nothing about cars, I was nervous that I was going to be conned into things I didn’t need. I was lucky enough to have Mike help me who was extremely professional, friendly, and explained in detail what I needed now and suggestions for services repairs that were not needed immediately. I never felt pressured but ended up doing everything. There is no other dealership I will use in the future!

Elco Chevrolet & Cadillac review
This is the fourth vehicle that we've purchased from ELCO
This is the fourth vehicle that we've purchased from ELCO Chevrolet, and there is a reason that I returned for my third Tahoe: they're the very best. Three weeks ago, I lost my husband unexpectedly and with two ELCO Chevy's, one 10 yr old Tahoe and a two-year-old Trailblazer that my children didn't want I felt it best to combine the trade-ins and purchase a new Tahoe that will take me another 10 years, providing me not only transportation but the security I need moving forward. The staff at ELCO were respectful, kind, understanding, and efficient. The purchasing experience was excellent from start to finish, and they took every step to make me feel like I was the only person in the dealership those two days. I am very grateful to Mark Gerecke and Branden Nehls for all they did to make the process as easy and comforting as possible given the circumstances. I am an ELCO customer for life.
2021 GMC Terrain SLE review
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.

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.

Ms. Mary S. Scialfa
CarMax made the purchase of my vehicle run smoothly, without having to go to the Division of Motor Vehicles. They addressed my concerns promptly and, when new keys had to be made, offered a "loaner" vehicle until the problem was fixed. I recommend CarMas to everyone!

I bought a 2013 Volvo and it needed a new blower.
I bought a 2013 Volvo and it needed a new blower. It did take a while to put in but the salesman I dealt with Zach S at the Econo low was very helpful. He kept on the mechanics and was put in. Not after having it only 3 days the check engine light came on and I am going to drop it off on Saturday and will have a courtesy vehicle to get by with until it is fixed!! I would definitely use Zach if you decide to buy a used car I’d ask for Zach S . He will definitely go above and beyond for you!! He even showed up on his day off to meet me!

Charlies was our salesman and was great to work with.
Charlies was our salesman and was great to work with. we came to test drive a truck & possibly trade ours in. He was informative and worked with us on the whole process. Deal went great and went away with a new truck to us and the trade in value we got on ours was within our expectations. Would go back again. Smooth transaction!!! Highly recommend Charlie!!
