Used GMC Sierra 1500 SLT for sale near Garden Grove, CA

Had to get some warranty repairs done. Jeff took care of all the processing and we were informed about the progress from start to finish. Professional, courteous customer service.

2024 GMC sierra 1500 duramax 3.0 is great truck. Great ride and great MPG. 100% recommend to any prospective buyer. Love the truck and how it perform.

went in for an oil change and was glad service manager told us about a recall on the sun roof. he took care of it immediately

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

I was in the market for the new Sienna XSE with some upgrades and couldn't find what I was looking for. I was in contact with A LOT of dealerships and they were just awful. I finally called Longo and was able to reserve a Sienna XSE that was coming from the factory, with the package that we wanted. David Fearn was awesome, he was understanding and helpful. We had a lot of question due to our previous experience and he was more than happy to help us. When the vehicle arrived we were a little afraid it would be sold from under us but again David was understanding and reassured me it would not. So we were able to relax and come in on our day off. I believe we spent about an hour finalizing everything and then drove home in our new Sienna. Its was such a quick and amazing experience, I definitely recommend Longo to anyone looking for a new Toyota.

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.

Enjoyed my experience here at this dealership. Came out with a brand new car! Anthony was extremely helpful and guided us to find the car we were looking for.

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...

Aaron helped my husband with his new vehicle purchase. My husband is very happy thanks !

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 have been here at Car Lux many times and have never had anything but positive experiences. Hard-working, ethical, and kind. Always fair, reasonable, and respectful Thank you.

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.

David Trinh had going out of his way to coordinate, communicate and followup with me during my order/purchase of my 2025 Sienna XLE. He even help me to set up my car after I already took it out of the lot weeks later. That's what cuatomer service is all anout... Thanks David

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

Everyone at Car Castle is wonderful including everyone in Management. Eddie in management was wonderful and assisted us with all the process. Come see them you won't be disappointed! 👍

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

I?ve been having my vehicles maintained at Selman for years and have never been dissatisfied. They do great work and keep you informed on your vehicle?s condition. The service representatives do a great job.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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

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.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

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!

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.

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 !!!

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.

Xavier, Sebastian, Aaron, and Nicole were all helpful and good to work with! Thank you!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

The experience here at Car Castle was by far the Best car buying experience my wife and i have ever had. Thank you Eddie the (Manager) for helping and assisting us with the whole buying process and for giving us a Great Deal!

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.

I purchased a truck for my business here after having a bad experience at another dealer. Aaron personally went to their second location to pick my truck up. Thanks Pacific

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!

The staff was friendly, knowledgeable, and never pushy. They answered all my questions and made the entire car-buying process seamless.

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Staff was friendly but i left without being able to have my app hooked up to my car and I was looking forward to that feature

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.
