Used GMC Sierra 1500 trucks for sale near Manteca, CA

Our sales associate, Fernando De La Cruz, was amazing! I really felt like he went the extra mile, which is a lost art in the auto sales world. I will buy wherever and whatever Fernando represents.

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

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 !

Greattttt!!!! Very helpful. Love my new car 2016 Hyundai Elantra. Albert helped very much. Test drove it was great. Paperwork went very smoothly as did the sale.

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 bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

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

Came from Merced because I seen your inventory and prices were great compared to other lots, salesman was not pushy, thanks Sargon.

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

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

pretty easy and seamless car buying experience, James Denegri was great, got me a good price, and got me the car i wanted. i was in and out in less than an hour keys in hand and smile on my face. The whole team was easy to work with and low pressure. i will definitely recommend my friends here and be back for my next car . THANKS AGAIN!

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.

The sales associate was very polite, knew her information regarding the vehicle I wanted to purchase and worked with me to accommodate my schedule which had to be changed a couple of times.

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.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

My wife and I had a great experience shopping for a vehicle for her at Modesto Auto Exchange. We shopped around at a few different dealerships in town for a good quality suv. We found a very clean ML350 with very low miles. The buying process was very smooth and we also purchased an extended warranty. They got us a really good interest rate with a local credit union. We’ve had the car for three weeks now and everything is going great. The owner and his staff is very honest and friendly. Thank you Modesto Auto Exchange!

I bought my gmc sierra in 2009 , brand new, and it’s the best truck that I have ever owned, and I have tried a lot of nice trucks, I mean i have owned a truck, Ford used to be my favorite , but it doesn’t even stand a chance up next to a gmc sierra like mine, my brother in-laws were very jealous about me owning it, my brothers all liked it, I have had a lot of pleasure driving my truck, and I have had very little problems with it, I’m retired now or i would buy another one just like it, gmc is the premier truck, it’s the very best, i love my truck.

Let's just say they have one of the best selection of trucks at the current moment in California, I don't know what their secret is but wow a good selection at a GREAT price. We came 6 hours out of our way to get a vehicle from here. They were easy to work with, and we had one hiccup and they were stand up guys and resolved it. You guys are a good honest business and should be proud of yourselves. Pat on the back!

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great customer service, reasonable prices, and before I bought the car they double checked the car on a machine again to make sure everything was running smooth. And they also put in a new battery and coils. I recommend this place to anybody who wants a quality good running car because they are very honest with you in the beginning.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

He is a Great Dealer and He Do's all he can to Help You find a vehicle that you would like to have and take for a test Drive. He do's not hang around you wile your looking for a vehicle and He also Dosn't Pressure you in to getting the vehicle of your Chose. But he is there to HEPL YOU if you would like him to Or also Answer any Questions you may wish to ask Him. He will also give you a caer Fax Report on any vehicle there on his Lot. There just Great People to do business with and it was a GREAT EXPERANCE L

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Very friendly and welcoming they took good care of me and my car. They gave us a time it would be done and was done at that time. Thank you for your honesty and kindness

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.
