Used GMC cars for sale near Guilford, PA

Moo Jim Addlesberger and Danielle were great to deal with while purchasing our newer car. Good experience all the way around. If you’re looking for a friendly, fair person in looking for your next car, look no further than Jim.

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Great service as usual. Friendly, knowledgeable service representatives. Very helpful give me detailed information on any questions that I ask. I will go back.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

I had a oil change and transmission check. The work was done quickly. The service lane assistant Alli Smith was very professional.All work was done well.

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Came in looking for a vehicle had a vehicle in mind took SUV for test drive went through the process and came home with it very pleased with SUV and the way I was treated would highly recommend Fitzgerald to anyone

It was a excellent experience. I recommend this dealership. And I recommend the sales person that worked with me adalberto Alcántara. He’s bilingual and he’s a very amazing sales person.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Very pleased! Purchased a Highlander Platinum used with less than 150 miles on it. Bargain of a lifetime. Justin Luttrell took excellent care of us.

I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

Service was excellent and the did everything exactly as they said the would! Very easy process!

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

The service department is excellent. I trust their advice and my service and repairs are carefully completed. I feel welcome and comfortable there. Thanks for the great work!

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

Great to deal with very happy with our new jeep and ram 1500 Nate my salesman was great worked with us the whole time and found just what we wanted and even helped meet my trades to the dealership the whole staff was great keep up the good work

One of the most attractive looking t cars GMC has ever designed. Looks just like a Lexus. Extremely roomy. Love every aspect of my Terrain.

Did not end up purchasing the car , but their communication was excellent. Would likely try them again.

2019 Canyon Denali. All sorts of bells and whistles, several that I don't really need. Biggest complaint: no memory seats and no Homelink garage opener. Ridiculous. What accountant made that decision?

Waiting room was clean service. Tinder was fantastic and mechanical work was done proper tim

The GMC Terrain is a very dependable auto that I have had no issues. The model is the AT4, which has the headsup display. Interior is nice with leather and all the electronics options.

The entire experience at Sheehy was awesome! From Kevin, the sales representative, to Clint, the manager, my entire deal was treated as if it was their own! They made every decision in favor of the buyer to make it feel I was being taken care of and treated right! Highly recommend the entire team at Sheehy VW in Hagerstown!

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Trent was the salesman that I dealt with, he was very respectful and helpful in my purchase of a car. He made the process very quick and easy on my end and he accommodated my schedule which was important coming from out of town.

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

I bought a 2016 Yukon XL and after just a few weeks, a vehicle ran a stop sign and totaled the vehicle. However, the vehicle was so sturdy that even though it was a huge crash, I was not injured more than bruises. I replaced it with a 2018 Yukon XL because I know it is reliable and safe.

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!

SMH was pretty easy to negotiate with on Dodge Ram 2500 we were not expecting to make the purchase that day, but they worked with us to return the next day to pickup our vehicle. We do have to return for a part that was on back order, and when it arrives I’ll give more feedback on the return for service. Thanks SMH

Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

I don't trust used car salesmen or dealers. I believe their general reputation for hype and dishonesty is well deserved. My experience with South Street Auto was remarkable not only because it contrasted with nearly every other used car dealer I have visited over many years. It was absolutely positive. This is a professional operation. Here are the details in brief. I went there on a Saturday to look at a 2004 Volvo, which was advertised at a price $2000 below book value. The test drive was good, and the car seemed to be exactly as they advertised. They said their mechanic had checked it out thoroughly. But I wanted my Volvo mechanic to inspect it. They were very accommodating. We agreed that I would tentatively buy the car, and they would wait to put through the paperwork until they heard from me by the end of the day on Monday. On Monday my mechanic found three items of concern: a noise in the alternator that sounded as if it were near the breaking point, a leak in the power steering reservoir, and a crack in the seating for one shock absorber. South Street Auto was surprised by the finding, but readily acknowledged that these were meaningful concerns. I proposed a compromise: they would replace the alternator, and I would repair the other two problems at my mechanic. Within an hour the salesman had the owner's approval for this compromise. They replaced the alternator with a new one the next day while I waited there. Bottom line: South Street Auto is a company with honest, decent salespeople who treat you with respect, and who are willing to admit a mistake and to help in correcting it. The car is terrific, and was a great value even with the $450 in repairs, and the experience buying there was first rate. Let me note that I am a real buyer, I am not a relative or friend of anyone at South Street Autos, and they did not ask me to write this review (and don't know I am writing it).

Friendly staff, great price for the car. There was a far bit of waiting around but with the volume of cars they are shifting on a daily basis, it was kind of expected. From the very short test drive to driving out with my car was around 45 minutes.Would definitely use then again.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.
