Used Car
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.
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.

Traveling to the Keys from NC with a troop of Boy Scouts
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.

I was having an issue with my vehicle and reached out to
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!

Kevon and Jason were great to work with. It was hard to understand the finance manager. Low talker and/or accent. I do not hear well so it could go both ways!

Review
Working with salesperson Brahms, made the entire procedure pleasurable. He made time to explain all of the features on the new Encore, with much patience. I decided to install side safety signals, and Brahms arranged for a loaner. Upon return, my personal belongs from the trunk of the car, were missing. Mr Brahms inquired daily about my belongings, and he went to the repair shop, where they were found, and he returned them all in tact. Commendable.
