We made our first purchase at Sun Toyota yesterday, and
We made our first purchase at Sun Toyota yesterday, and it was an outstanding experience from start to finish. Mike Devito went above and beyond—he didn’t feel like a typical salesman, but more like a trusted friend guiding us through the process. Everything felt easy and relaxed, with zero pressure. The dealership is stunning, and their selection of pre-owned vehicles is impressive. We drove off in a beautiful 2021 Nissan Murano and couldn’t be more thrilled. It truly feels like we’ve joined the Sun Toyota family!
I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I worked with Johnie S.
I worked with Johnie S. and I would highly recommended him to anyone looking for a new car. Even when we were in the heat of negotiations he was polite, respectful, and transparent. Are negotiating via text on a specific vehicle he was able to send us all the documents over email and got us in and out of the dealership in 90m. Wayne in finance was extremely friendly, pleasant, and made a typically painful process painless. It?s clear the manager Steve has this place running smoothly.

We have a Ford Fusion since 2017 and it has been
We have a Ford Fusion since 2017 and it has been fantastic vehicle for us. In past week we had repair done on fixing the electronic security system, connected to the edge of driver door that was not operating correctly. Josh helped me with identifying the issue and also Jack. Veterans Ford did their analysis and tests to get to the root cause with their specialized technicians in the electronics area. We were very concerned as this issue is very critical for us to function correctly. I am so happy that the Ford team at Veterans got it fixed and all is running perfectly again. Because the issue was intermittent it made the challenge even more difficult - so my thanks goes to the whole team who made this repair a success. The team there takes the time to listen and help their customers to the very best of their ability. When I was in Ireland I went with my Dad to a Ford dealer there, where he bought his first car a Ford Anglia. Ever since then we have stayed with Ford for many years. I was given ride to and from my home a few miles away. I have no hesitation in recommending Veterans Ford to any customer. Patrick O’Brien
2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

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!
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Highly recommend Rivard GMC Buick.
Highly recommend Rivard GMC Buick. Haley was our sales consultant, and provided a no pressure, no games sales experience. Straight forward pricing, without all the money making add ons. Family owned business as well.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Love Gator Ford
The only place I’ll take my car to get serviced. I’ve had a couple different service writers through the years and they’ve all been awesome. I always feel very comfortable there. I’ve never been talk to you like I’m stupid. And if any woman knows ….we get that a lot when we deal with car places! Thankyou Nick for making my day less stressful again!!
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.

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!
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Excellence from Start to Finish
Exceptional experience from beginning to end. If you're looking for excellent customer service, no pressure sales, transparency and a genuine caring for their customers you have to go to Lokey. Austin Surette is an outstanding sales consultant. He listened to our needs and worked with us to ensure we received 5 star service. He exceeded our expectations and went above and beyond. Celebrating over 70 years of excellence in the automotive industry, Lokey continues to embrace the values set forth by its founder and remains a family owned and oriented business. Every member of the team always greets with a smile and "see what I can do" attitude. So refreshing from what you might experience elsewhere. A special shout out as well to Brian and Danny in service who have always been no less than amazing. Our entire family has vehicles from Lokey and couldn't be more satisfied. Thank you to everyone at Lokey ~ you are all immensely appreciated!

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.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!
