Great New Car Shopping Experience!
Logan Gleason made our new car shopping experience easy. He did an awesome job showing us vehicles that we might be interested in based on our criteria. He answered all of our questions and, if he didn't know the answer, he quickly found out the answer. He even went as far as answering questions via text while he wasn't working. He was very knowledgeable and extremely personable. The financial part of purchasing the vehicle was the easiest that we've ever experienced - thanks Jeremiah. We love our new Nissan and have already received many compliments.
This truck has a jerk when changing gears sometimes.

Vehicle Service
Stopped in for an oil change was there for just about an hour. In addition to the oil change my tires were rotated. This was my first experience with Hagerstown Ford, I was very please with their service.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Great Pre Owned Vehicle!
Kyle and the Massey Hyundai team sent me away satisfied in my Pre Owned Tucson! The process ended in a flourish as Kyle answered questions to my satisfaction then handed me off to Nick and RD the next morning. Great teamwork. Great used vehicle and great experience, all boxes checked! Thanks Gentlemen.
Diesel AT4 it!
GMC Diesel Canyon AT4. I've had this truck for a year-11,000 miles. I love it. The Denali and Elevation trim looked like junk. The AT4 can't compete with the Tacoma off road but, It holds it's own off road. The Diesel pulls like a beast and the exhuast brake, on all the moutain passes I drive, is worth it's wieght in Gold. I trailer the max. capacity regularly and it's smooth sailing. I traded in my 2500HD Silverado with the vortec 6.0 for this big, little truck. Best decision I've made in a while. I had this truck on order for 8 months and Gm never accepted the order. I finally found exactly what I ordered, just off the truck that morning that I called. 1300 miles away, I jumped on a plane to go get it. Crying shame GMC discontinued the diesel. The extra $ per gallon right now is easily washed by the increase in mileage, 32+ higway, 19 trallering almost 8000 #'s. I wouldn't want the truck without it. Wouldn't want the Elevation or Denali. Diesel AT4 is the truck. I'll keep it the rest of my life barring accident. I'm sure I can get 40 years out of this truck doing 10-12k a year. The regeneration of the exhaust has never come up but, I only do a little round town driving. Most of my miles are highway and hauling a load. I've heard horror stories about regen. from city folk, commuters... You get what you aim for. If you've given it a lot of thought and the diesel AT4 seems right for you, you won't be disappointed. Good luck finding one. GM - You've a winner here. don't let it get away. Ps. Cars.com doesn't have a choice of how I use this truck for WORK. And wouldn't let me submit this review without selecting one of thier 3 inadequate choices. So, I selected having fun cause I believe everything should be but, this is my WORK TRUCK!

JC was awesome in all aspects of the buying experience. Overall highly recommend Younger for your next auto purchase.
Stylish and comfortable.
Just purchased this vehicle a little over a month ago. Love the ride, the comfort of the seats, and, the body style. My only complaint is that it drifts to the right and the steering wheel is several degrees to the left after two trips to the dealer where we purchased it. I will probably have to pay to take it to a known, excellent alignment shop.

September 18, 2025 was the second time I scheduled an appointment with the Service Manager David Gray at Shively's. I rank David Gray at the top of Service Managers. First, he is kind and caring. His demeanor rings with kindness and heart. I noticed David treated each customer as if the customer were the only one getting service. His voice is cheerful and so genuine and he listens ti customers. Second, he is extremely professional and knowledgeable about the services Shively's offers and the service a customer wants and needs. Third, it is obvious that his technicians and office staff respect him. Fourth, when I left Shively's Service Department both times, I was confident that David Gray and his technicians had serviced my vehicles with the utmost expertise and care. Fifth, David Gray is proud of Shively's and proud to serve Shively's. Outstanding service!

Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

Awesome Ride!
I got my Acadia AT4 used. I was attracted it for its rugged look and it is fully loaded. I was downsizing from a Traverse and this one fit the bill. I love all the safety features, the way it drives, and the power from the V6 engine. It also includes Android Auto, which I use all the time. I was able to transfer my OnStar plan to this as well and am totally happy with my purchase!

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white
