I had a great experience with the process of returning my leased vehicle and selecting a new one. Having owned and leased several Chevys over the years, this was actually my first time at Tim Lally, so I wasn’t sure what to expect. Justice was my salesman. He was courteous and helped me find the right vehicle. The management team were equally impressive and able to negotiate a price point that fit my budget without resorting to high pressure sales tactics. Not sure why I waited so long to check this dealership out, but I will definitely be a repeat customer! PS - love my new 2026 Trailblazer.
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!

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.

Sheehy always strives to provide the best service
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.
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.

Everything but the cookies.
If I had to find something to complain about, it would be that the snickerdoodle cookies in the lounge area were not as soft as I would have liked. I will continue to return to Brenengen Sparta to have my truck serviced as long as I live here.

I would recommend Principle Volkswagen with a caveat - once you get into Service, everyone is great and we've never had a problem with Service. I like the video from the mechanic showing and detailing what was done. However, reaching them on the phone is a nightmare. The phone to Service rings and rings, then disconnects. If you can finally get to a point to leave a message, they are never returned.

I live on the west coast and bought my Ford F-350
I live on the west coast and bought my Ford F-350 "remotely" from Granger - and could not be happier with my experience. Although there was a production delay on Ford's end, Samantha at Granger keep me regularly updated as to status. And once it came time to do the required paperwork Shelby at Granger was also extremely helpful and responsive. In summary - a great price and great team made this the most hassle-free, enjoyable vehicle buying experience imaginable.
