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.
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.

Jesus, who handles the internet request, was prompt to respond to my inquiry, and was waiting for me when I arrived at the dealership. Answered all my questions, very professional, helpful and yet friendly.
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.

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.
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.

I can’t recommend this car dealership enough—from its Dealer Principal Chris Napleton to the Service Manager Chris Cantù to my service advisor Lili Welker—it is evident that excellence flows from the top down. From start to finish, the experience was outstanding. They are professional, knowledgeable, honest, and genuinely cared about making sure everything was handled the right way for my family. They took the time to clearly explain what my car needed (and what it didn’t need), kept me updated throughout the process, and made the entire experience smooth and stress-free. It’s rare to find a dealership that combines expertise with great customer service, but they absolutely nailed it. My family has purchases three Hondas from here in the past 2.5 years. I always feel respected, informed, and confident that my car is in great hands. If you’re bringing your vehicle here, do yourself a favor and ask for Lili—you’ll leave feeling taken care of. Five stars without hesitation!

Good service.
Good service. The buying process was a bit hectic but that was because I was trading in a car with an out of state plate and then the weather slowed everything down. There was an issue with my tire after I purchased the car and they fixed it for free luckily.

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.

Jojo and Greyson were phenomenal! They eased my concerns and walked me through the process of my car repair, all while my husky was in need of her monthly arthritis pain shot. (Which due to them she got!) I highly recommend their dealership, and this is where my business will stay for all my auto repairs including any and all future auto purchases.

I’m not typically one to write reviews, but my experience
I’m not typically one to write reviews, but my experience with CarMax has been so outstanding that I feel compelled to share. From start to finish, they’ve redefined my expectations for buying a vehicle. I found a car online that checked every box for me—low miles, all the specs I wanted, and fantastic photos that gave me confidence in its condition. The only catch? It was located at a CarMax dealership in Florida, while I’m in Nashville. For just $200, they shipped it to my local CarMax dealership. Knowing the worst-case scenario was losing that $200, I felt reassured to take the leap—and I’m so glad I did. Within just a few days, the car arrived. I had a trade-in—a mid-mileage VW Atlas in good condition—and to my surprise, CarMax offered me an amazing price. I’ve done my research, and they gave me a value that was very close to what I’d seen comparable models selling for, and significantly more than I owed. Needless to say, I accepted their offer with ease. As for my new (used) car, I was impressed by the comprehensive warranty options. The extended warranty they offer feels like an insurance policy: $200 deductible for coverage up to 150,000 miles. With my car’s mileage at around 50,000, this was a no-brainer. I’ve seen glowing reviews about the warranty online, and after my own experience, I can see why. Now here’s the part that truly sets CarMax apart—the post-purchase experience. The vehicle is used, so it’s impossible to catch every little thing during a quick test drive. Thankfully, CarMax provides a 90-day warranty and has a full-service garage. I’ve been back a few times for small fixes, like the gas door not working properly, tire monitor sensors, an alignment issue, and even replacing a rear entertainment system screen. Every single issue was handled promptly and professionally, leaving me with a car that feels brand new. Shoutout to Elvis in the service department! Not only did he remember my name when I returned, but he also ensured I had a free loaner car anytime my vehicle needed to stay overnight. The customer service I’ve received from him and the entire CarMax team has been nothing short of exceptional. This entire process has been so seamless that I can confidently say CarMax will be my first stop the next time I’m in the market for a car. I’ve purchased brand-new vehicles before and never felt this satisfied. CarMax has raised the bar for what car buying and ownership should feel like. If you’re on the fence about where to purchase your next vehicle, I can’t recommend CarMax enough. From great trade-in offers to their stellar warranty program and impeccable customer service, they’ve won me over as a fan for life. Here’s hoping they stay around for a long, long time—because this is how car buying should be done.
