I just bought my GMC Canyon from Ed Morse GMC, and
I just bought my GMC Canyon from Ed Morse GMC, and working with Juan Tabares was the best car-buying experience I’ve had. Juan was friendly, honest, and completely transparent — no pressure, no games, just straightforward answers and a smooth process. The whole team was welcoming and knowledgeable, and unlike many dealerships, there was none of that “pushy salesman” vibe. They focused on clarity, making sure I understood exactly what I was getting and that they understood what I wanted. If you’re shopping here, do yourself a favor and ask for Juan by name. He’s professional, efficient, and will make sure you leave happy.
This truck has a jerk when changing gears sometimes.

Sales experience
Well, I was on a waiting list for the corvette c8 but once it came in I was notified that it was here and my salesman stayed in contact with me until I was able to come in. He took the time to accommodate both me and my wife and was very professional throughout.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Purchase of brand new 2022 Atlas VW

Great purchase experience
Due to another dealer bait-and-switching me, I contacted these guys over the internet regarding a listed price in order to make sure they’d honor theirs before making the 50mi drive. Not only did they honor it, but the entire test drive, negotiation and financing experience lasted less than 2 hours. Top notch!
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

The other reviews here are penny ante, very minor stuff.
The other reviews here are penny ante, very minor stuff. I asked Lisandro for an out the door price and I got it fast, with options to help me with financing and shipping. Most other dealers are very slow and never give that price. Performance Mitsubishi's price was $12000 more than advertised. Give both a chance and you will do business with Lisandro. Spend a couple minutes and see. Besides being GREAT to deal with, test drive the Outlander. It drives better than the Rogue and is crazy cheaper than Toyota. It is nicer inside too. Don't buy a turbo gas car. They don't last as long. Buy an Outlander from Lisandro and you will get the deal and be happy with your car.

I seen alot of negative reviews here and honestly dont know why!! They have been awesome to me and were very patient. I think maybe people are upset over their fees but no one works for free and the fees are listed... Worked with Brandon Martinez and it worked out great. Just be sure to do your homework first thats all and you will be 100% here. I also think their positive google reviews are more accurate than the cars.com comments tbh.

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.
