New and used 2026 GMC Terrain for sale near Palm Beach, FL

I was having an issue with my vehicle and reached out to a few dealerships for help. One never returned my calls, and another quoted me an outrageous price without even looking up my vehicle. Then I got Ethan from Sheehan on the phone, and everything changed. I was frustrated and flustered, but Ethan immediately took the time to calm me down. He looked up my vehicle and let me know the repair would be fully covered by my warranty. He even asked if I could bring the vehicle in right away. When I arrived, Ethan went above and beyond. He made sure the team drove me to the rental car location?even though it was right across the street?because it was a busy road. He also ensured that my rental was covered under my warranty. He kept me informed throughout the process and assured me the repair would be handled quickly. True to his word, my vehicle was ready the very next day! It?s rare to find a service advisor who genuinely cares and follows through on their promises. I?m so glad I didn?t give up and called Sheehan. From now on, I won?t waste my time with any other dealership. Thank you, Ethan, for the outstanding service!

Scott Crowder took time to go over my needs as I was researching a used car. When I make my final decision he will be my go to.

Traveling to the Keys from NC with a troop of Boy Scouts my new battery (three weeks old) failed in Titusville. I replaced the battery but between Titusville and West Palm my battery voltage gauge started to drop. I stopped into Schumacher Buick GMC to check the battery and charging system to ensure I did not have an electrical issue. The shop had a full day of appointments, but the front staff worked with the shop to squeeze me in. Within an hour Rob, the shop supervisor, troubleshoot my car, ensured me that the electrical system was working properly and got me back on the road. Thanks.

Larry and the whole team were professional and made the process of purchasing a new car an exceptional experience. I will definitely will consider going to them to purchase any other vehicle my family need. Thank you, Zulma Hawkins

Gary Sanchez made the buying process straightforward, fun, and easy. I would highly recommend working with him if you are looking for your next GMC or Buick vehicle. Nice, smart guy.

Brandon consistently goes above and beyond, ensuring that any unforeseen issues with my car are thoroughly addressed. He provides clear, accurate explanations, making the entire process smooth and stress-free. His commitment to superior customer service truly sets him apart, making every visit a great experience. Highly recommend!

Seemed to be good folks but they did low ball trade in value on my C7 2019 Corvette with 3LT. Others had offered $3-$4,000 more but they dd not have trade I wanted. So I passed.

Brandon is the best advisor . Keep me informed and handle my issues very well . Return my vehicle back to in better condition than I brought in to the dealership . Great service and great people .

Response to my inquiry was prompt and courteous. So was the follow-up as the sales agent checked with me regularly. The initial internet presentation of the car wasn't great as pictures were of "other" cars of the wrong color, etc. I didn't buy the car so I don't know what happened after a few days.

Joey, Mark, and Mike were all great! Easy transaction highly recommended! My lease is coming up in a few months and I would strongly consider dealing with these guys again!
