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!

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

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!

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.

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.

Very helpful, no pressure, great prices and willing to work with you to get the best deal ever!!!! Nico covered all of my concerns and answered all of my questions.
