Excellent team to work with across the board.
Excellent team to work with across the board. The entire process was painless albeit time consuming. Would definitely recommend for anyone looking for an easy to work with team.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

I actually really like Lake City Buick service dept.
I actually really like Lake City Buick service dept. Not only are they friendly but they go out of their way to make you feel at home . Robbie is always straight up on what needs to be done to my truck, I pass two dealerships I used and never get the service like Lake City gives. I drive 80 miles to get my service work done there. Thanks for being a great dealership. And thanks for Robbbie and his coworkers

I had an incredible experience at Tasca GMC in Palm
I had an incredible experience at Tasca GMC in Palm Harbor. From start to finish, the entire team made the process smooth and stress-free. A special shoutout to Lenny — he was absolutely amazing to work with. He was kind, patient, and really took the time to make sure everything went perfectly. It’s rare to come across someone who truly cares the way he does. I’m extremely grateful for the professionalism and customer service I received here, and I’m looking forward to working with Lenny and the team again in the future. Highly recommend!

I drove over 1,000 miles to come to this dealership and I’m glad I did. They took care of us quickly and were very communicative throughout the whole process. They sent me pictures and videos so that I could know what I was getting even with being far away. Great group of people and very friendly and hospitable. Would definitely recommend this dealership. Thanks Staton for the easy car buy.
