Buick GMC Brooksville review

Sal is an awesome sales agent, pleasure to work with.

Sal is an awesome sales agent, pleasure to work with. Not overbearing, very knowledgeable and friendly. With his Long Island accent I felt like I needed an interpreter at times. Lol Thanks for a great encounter

2026 GMC Sierra 1500 AT4 review

A little expensive, but comfortable, quiet, smooth ride.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Ferman Buick GMC review

OK, I have purchased mini new vehicles, but this is the first time ever buying a new domestic Auto Mobile a 2025 Canyon elevation I have owned a number of trucks Tacoma Nissan Dodge. In the moment you drive a canyon you know why you’re getting it. I left a very good deal with a new Tacoma and just have to run with the canyon Now the Furman GMC here in lutz Has certainly been stellar over the last eight years in Tampa I’ve had to get into nearly 2 lawsuits with dealerships over violation of administrative problems, horrible finance practices, and below subpar service departments It was really not sure what to expect with this dealership, but in the end, I may have very well found a new home Alec, my salesman has been attentive, polite and not pushy. He’s been responsive and on top of things since I purchased the vehicle. Earnest and finance is by far the best example of professionalism that I’ve ever had and I mean, ever had with a finance department he was thorough. Sincere personable, was not pushy did not give half-baked answers and was very open and forthright in our discussions. It was an incredible experience. Ernest is definitely the finance guy we all need. Service I have Ryan as my service coordinator and he has been nothing but pleasant astute, and on top of things, caring and pleasant so far my interaction with the service department has been stellar along with the parts department, which I had very limited interaction but so far absolutely no complaints As far as the durability and reliability of the GMC canyon time will only tell I hope that it will provide me years of fabulous service while I expect occasional things to break or need to be repaired. I trust and hope that the Americans can make a vehicle that at least challenges the Japanese. This vehicle purchase in every aspect has been incredible. Great job Furman.

Cody, my salesman, was professional, helpful, honest, and a pleasure to work with. There was no pressure at any point during the process. JP, the sales manager, was also easygoing and pleasant to work with. They were both very accommodating in negotiating a fair price—They even allowed me to inspect the underside of the vehicle, which I really appreciated.
