Used GMC cars for sale near Montclair, CA

I highly appreciate the professionalism and efficiency at STG Auto Group. Maria made sure I was accommodated throughout the whole process. She was polite and always elaborated when I had questions. I’d highly recommend going to STG Auto Group for your next vehicle purchase. Ask for Maria, she made it easy.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Called to verify that the car was in their inventory. They responded kindly and told me that it was available and that I could give it a test drive if I pleased. Went and drove the car and liked it very much. The financing was very easy and fast. And they don't try to up sell anything else. I didn't feel nervous doing business with them and made sure that I was taken cared of. I would love to come back and do business again with Abraham and the boss.

sturdy and reliable, handles city driving well. mountain driving was good, braking was very good. stereo was o.k. very good viewing access all the vehicle. engine had good power.

Dominique is very good customer service in my buying today for the Ram 2500 working with him was very easy

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

This was one of the best experiences I had purchasing a vehicle everyone was kind a very knowledgeable. This was the quickest I've ever purchased a car thank u !!!

Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

Well I went to check out the cars dealership is pretty clean cars are excellent but I couldn't find a car that fit my needs

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

They really try to make everything work for us and even if I was tired they try to take care out us

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

Not happy with the degree of energy some employees/ sales people were and most likely won’t come back or recommended Although Dom Was excellent With his communication and care He was one of the only one here with people skills

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Austin, Zach, and Jaime were exceptional , they got a a great deal would definitely recommend to family and friends!

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Keshan and Hamsa were Great through the whole process fast and quick will definitely buy again

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Excellent service here. Totally professional and very kind. I have nothing but positive things to say about them. Thank you very much David and P!

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

I experience very good service at Norco Truck Center.I end up buying a 2012 ford 150 4x4.I also found cars .com very useful

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Love this place , love the service, love how fast my process was to get into my M4 .best dealer I’ve ever made business, super polite , humble and very respectful, they even car washed the vehicle, man come one I was like whatttt!!! Super happy I drove out from Hollywood and I was not disappointed. Check it out for yourself!!!!!!

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

After getting the run around from multiple dealerships in LA/OC/IE I visited Auto Republic. Yes, I had my guard up after all the financing and heavy down payments other dealerships we're asking for before even giving me attention. The showroom was clean and the lot had so many dream cars. I found the perfect car for my family and had the assistance from the manager that was top notch. I'm writing this review since the single star reviews show the lack of reading details about add on features. Don't get upset with a dealership for having tracking on a car (saves on insurance) along with other key options that are great for your next car. I've referred family and friends, all had exceptional purchasing experiences and I'll get my next vehicle here as well.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Kris was great! Had a lot of patience with me and definitely will recommend him for your next car purchase.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

There was a chevy 4x4 van we needed since we plan on moving to Colorado and need it for the snow. There wasnt that many I could find but this place had it. No complaints good seller here.

i own 2 of them in my business. good for hauling people or cargo. tows a trailer with ease. very reliable. and decent on gas.

Got right to me after asking questions I am shopping for a used van they gave me good answers and were courteous

Very reliable. Powerful. Great style, has a cult following. 8 seats, AWD, plenty of space, strong towing. Unstoppable in snow. Poor MPG.

i got a 2009 nissan versa . i had a good experience shopping for my new car here. thank you guys

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

muy buen servicio, kris me atendio consegui la gmc muy buen trato me hiso lo recomiendo

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Albert was great in assisting me with my new Tesla! Couldn’t have asked for better service.

handles and drives great, the electronics don't always work, mirrors don't always work, spray with wd 40, check engine light, EVAP culprit, auto nation has no luck with this, will drive it till the warrenty expires and its back to ford for me
