I had a check engine light that needed to be worked up.
I had a check engine light that needed to be worked up. The service rep made the diagnosis quickly and explained everything. He also noticed that much of the chrome trim under the windows on both sides of the car was loose (2023 Kia Telluride). He said they would have that replaced for me while I was there. Overall a great experience
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!

Great experience
My boyfriend bought his car from Carmax and it was a great experience. So when I needed a new car I looked at Carmax as well. They had everything I wanted but I thought I would get a better deal at a dealership... Boy was I wrong. Went to three different dealerships almost went through with a deal but they couldn't get me a good interest rate. It was so painful and awful I had decided to give up and just sink money into my current car and try again next year. I had an appointment at carmax the following Sunday and Dwyane called me to verify the time. I told him what happened the previous day and said I would be keeping my car because I needed a good rate and didn't want to be making crazy payments. He said, I hear you and totally understand, I'm happy to help you whenever you're ready. Just so you know when you are ready I have a good rate for you so I know we can find you something to make you happy. I was surprised because the other dealership said we couldn't get close to what I needed. Well folks, I'm in a new car, my payments aren't crazy and I have peace of mind. We are Carmax people from now on. Thanks Dwayne in Clearwater!

just now New Excellent experience from initial visit to picking up my GM certified truck! Note we aren’t local to the area but live 97 miles south of the dealership. It was worth the trip 👍 I really appreciate how the team at Tasca listens to you rather than try to bulldoze you thru a canned process like most dealers. They were flexible and responsive to how I wanted to evaluate the vehicle I was interested in buying and my timeline. Have to give shout outs to so many individuals. Cassandra promptly responding to my internet inquiry, Dillon the sales manager setting up my first visit, Nolan my sales professional meeting me for the test drive then taking care of everything up to final delivery and Melvin the finance manager who made sure the money part went smoothly. I know there were others behind the scenes who am thankful for as well. Definitely recommend! Would definitely buy from them again. Worth the drive & time!!

Juwal, Travis and financing or seamless and didn’t harass us to add add-ons because I told what my budget was upfront and when I needed the car to do and they found that car and they made it fit my budget and I’m talking about cash budget out the door cause I don’t do car payments They are lovely lovely people they’ve called to check on the car and me and my daughter because we need the car for the safety features because of our medical issues this dealership treats you as though you are family which is greatly appreciated in a really cruel world.

I has my NX250 serviced today.
I has my NX250 serviced today. My advisor was Jose. Prior to having my car serviced he explained everything to me and stated that it would take approximately an hour and a half. I also had a question about my audio system and he was able to answer it right away. My car was returned to me faster than Jose had started washed and ready to go. Jose was fantastic and I would highly recommend this dealership for all your needs.
