Arthur Morgan was an excellent salesman.
Arthur Morgan was an excellent salesman. He made things quick and easy. It was, by far, the best dealership experience we have ever had. We made one phone call to him, drove to the dealership and he already had car detailed before we even bought it! Knowledgeable and experienced staff.

Overall great dealership. Love Staff in Service dept and my personal sales rep, Richard ? looking forward to my new 2026 Equinox!!!! Yes Yes okay okay
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!

I am very hesitant to trust anyone in the car selling
I am very hesitant to trust anyone in the car selling business. Not a great reputation overall. But I had a great experience with this dealership. Ed Popp was great.
Gas and diesel terrain
I have owned 5 of the 2018-19 terrains. I have had the 1.5 gas, 2.0 gas and the 1.6 diesel. The power on the 2.0 is awesome. Mileage on the 1.5 is good. Mileage on the 1.6 diesel is great. I have 336,000 miles on my diesel. It has had lots of issues due to emissions and transmissions. Last week it got a new engine as well. The car is a great car but I would recommend the 1.5 gas for most people. The terrain is comfortable and makes a great work or travel vehicle. Size is easy to park with plenty of leg room.

My GMC Terrain saved my life.
Great savings on gas and mileage, very reliable and comfortable. Saved my life when I was in a big rig truck accident as driver side and front side bags deployed. I've become a GMC customer for life as I will be looking forward to buying another GMC SUV.

Luis fue muy amable honesto y mas que todo la calidad del trato nos iso sentir muy bien muchisimas gracias Te recomendaremos a nuestroa amigos y familiares
We love this automobile.
This is a higher trim model with the bigger 4 cylinder engine (2.0 vs. 1.5) most of the options including Bose sound system. We love our pick and the only reason I gave 4 stars to comfort is the ride. Granted it rides nice, but you only get 5 stars from heavier sedans. Trucks and SUV's just aren't designed for that really smooth ride. Definitely would recommend the 2.0L engine if you tend to pass on a 2 lane road or need to pull out quick in traffic.

Great Experience
We bought an Audi Q7 from Marcella. She was friendly and upfront. The dreaded finance office even was pleasant. Car prices are what they are. I’d buy another here. Was disappointed with the 1/4 tank of gas lol I left more in my trade. And no inspection sticker. But overall great and those 2 things would not deter me.

First purchase from Penske Chevrolet but won't he our last. Penske helped us find and buy our exact dream car, even though it was many miles away. Plus, they helped us get the right kind of financing to make it a reality. No high pressure sales - just competence, professionalism, great communication, and kindness!

Sheehy always strives to provide the best service possible. Their service team is top notch and they keep you advised on the status of your vehicle while being serviced. One of the best things I’ve experienced here is that they don’t try to sell you any services that your vehicle doesn’t need.
