Worked with sales associate Joseph Rodriguez to purchase
Worked with sales associate Joseph Rodriguez to purchase a 2019 Santa Fe for our daughter. The process was seemless, Joseph was paticence and had the answer to our questions. We are very happy with the purchase and with Joseph's patience.

Khader
Khader was very helpful. I came in looking for a car with a huge balance from my previous car and he helped me get into a newer car and helped me achieve the payment I was looking for. They are all very helpful and they are not the typical pushy salesman. A very nice establishment to purchase a car from. Thanks again Khader!
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

LG as a dealer was cooperative and polite.
LG as a dealer was cooperative and polite. The salesman, Mike Amarando, was professional, personable and proficient in his job. Good man to deal with. We could not reach a sale but that was because of the car that did not meet my expectations.

Great Dealership!
I bought my Buick Regal Tourx in 2019 from them and they have helped me maintain her since. Awesome dealership, and recently Bill in service has went beyond the wording or meaning of service. My Regina drives just like she did out of the showroom 4 years ago. Kudos to T and T Coast and Bill in service!

I’ve had a great experience so far.
I’ve had a great experience so far. I purchased a pre-owned Ram last night. My salesman was Eric. He’s super friendly, personable, and professional. He made me feel valued even though I wasn’t buying a fancy, new, expensive vehicle. I was in and out, hassle free, and on the road very quickly.

I purchased a used vehicle on May 10 of 2025.
I purchased a used vehicle on May 10 of 2025. I actually started the purchase on May 1, but it was for my business and took a little bit longer to secure funding, etc. I work with Frank, who was amazing. He was patient, kept me informed, helped me along in the process, and delivered the vehicle so smoothly. Zach, the finance gentleman, was also amazing. The entire process was smooth and easy, and I would absolutely go back.
