Excellent experience at McGee Toyota of Putnam!
Excellent experience at McGee Toyota of Putnam! I want to highlight the service from Crystal, my Service Advisor. From the moment I arrived, she was extremely friendly and professional; she explained everything clearly and kept me informed at all times. Beyond being very efficient, she has a kind and personable demeanor that makes you feel at ease. She made sure the entire maintenance process for my vehicle was quick and hassle-free. It is hard to find such dedicated customer service these days. Five stars for her!
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.

The work was completed in a timely and quality manner. The vehicle is a 2018 Denali HD Diesel. The crew used GMC rebates and incentives to help minimize the cost to me.
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 felt they were honest 1st of all.
I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.
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.

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 a new 2026 Dodge Ram truck in December. The process was fast simple and very pleasant. No pressure from the salesman on buying it. Will definitely recommend this dealership in the future. Oh and if you need an explanation on all the buttons ask for Vince he was great to work with!

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 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!

I recently went to the Honda dealership in Westminster a couple of days ago because my sliding door was having issues—and of course, it was raining that day. I want to give a big thank you to my service advisor, Renae Franco. She was super nice, professional, and genuinely helpful. Even though my sliding door wouldn’t close and it was raining, Renae went above and beyond by wrapping the entire door with a plastic nylon cover so rain wouldn’t get inside my van while I drove home. She didn’t have to do that, but she did anyway, and I really appreciated the extra care. A few days later, I called back to follow up and spoke with a supervisor named Henry. He was also very professional and took the time to work with me to help resolve the issue. You can tell he really cares about customer satisfaction. After this experience, I feel confident trusting this Honda dealership with my vehicle. They’re honest, professional, and willing to work with customers—something you don’t find at every dealership. I would definitely recommend this place to anyone

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.
