Ask for Bradley B.
Ask for Bradley B. at Regal Honda of Lakeland, he is the best! He goes above and beyond for his customers and tries to help as much as possible. He is a professional and polite salesperson. There was no-pressure and I didn’t feel rushed. It was a very positive car shopping experience.
This truck has a jerk when changing gears sometimes.

I saw a vehicle on Carfax that I was interested in and made an appointment to check it out. Kent did a great job of showing me the vehicle and worked with me to a deal that fit my budget. I returned several days later to pick up the vehicle and Kent wasn't in, but Jose stepped up to help complete the deal and made sure I got the truck and went over all the details of the truck's operation. I had a very good experience. John K

Too much overhead and one too many times the salesman
Too much overhead and one too many times the salesman going back and forth to ask mother may I. The management is not customer friendly and it leads to many distractions. Revamp your business.

I just purchase a car from these guys.
I just purchase a car from these guys. From the moment I called, they had the car pulled up front. To the test drive with Jose'. Very easy person to talk to. To the credit manager, office manager, to the owner. They were all easy to work with. I have never had a more comfortable experience puchasing a car. Just bring your info with you, they even transfered a tag right then in there. I was looking at a few other dealers before going here. I'm sorry I waisted my time with the others. I would tell everyone to go here. Best experience ever!

I had an excellent experience at Kelley Buick GMC.
I had an excellent experience at Kelley Buick GMC. From start to finish, the team treated me with professionalism, honesty, and respect. They took the time to answer all my questions, walked me through every detail without pressure, and made sure I got exactly what I was looking for. A special thanks to Gustavo Sanchez and Russell Hernandez — both went above and beyond to make sure the entire process was smooth and stress-free. They were knowledgeable, patient, and genuinely cared about finding the best fit for me. The finance process was straightforward, the dealership was clean and welcoming, and I never once felt rushed or “sold.” If you’re looking for a dealership that values customer service and treats you right, Kelley Buick GMC is the place to go. I’ll definitely be back for my next vehicle.

Javier was transparent, kind and efficient.
Javier was transparent, kind and efficient. Will honored a $1000 drop in price that occurred the evening prior to my arrival in Tampa. Randy was very professional and knowledgeable about the financial part of the sale. I’d consider making the trip from South Carolina to Tampa for my next truck. The whole team was smiling, helping one another with their potential clients, and didn’t hear anyone speak negatively about how their day was going. Seems like the team worked well together and the culture was like a family. Keep it up CarHeroes!

SUPER DOOPER CAR SERVICE
I just got home. I left my house at 7:30 this morning and was at the dealership for five hours. BUT I had asked them to do a complete assessment and they did everything. I love these people. As I drove up my little four legged service person got all excited. She knew where we were and she has a lot of friends there. Everybody came out to greet us and help us descend. As a rule I am treated as someone special. I'm not but I am 87 years old and they are careful to take good care of me. I know them all but am losing my ability to remember names so please forgive me guys but Roderick, Arsenio, Luis, Denisa are so kind and I wrote down their names so I could remember them. My car was very happy and I don't know what all they did but she was very happy. (Yah! She's a lady). I have a very serious suggestion: Now I have no intention of ever buying another car , BUT, wouldn't it be great if you could go to a dealership, (as a woman not knowing much), and find a salesperson there, (of the female persuasion) who not only knows cars but knows the mechanics and has been taught the correct way to sell? I would scout places that teach car mechanics and see if a female is part of the student body and offer her a course in selling and a job. Maybe she just wants to be a mechanic but you could still call on her when you have a woman to sell to. Just an old lady's idea. I encountered a super female salesperson at a Honda dealership in Kissimmee, FL about 25 years ago. The only reason I didn't buy her car right then and there was I had decided I wanted a Chrysler. Anyway, You guys get all the stars. I know i can trust you.
There are 20 matching cars close to your year range.
