Used 2023 GMC Sierra 1500 trucks for sale near Lake Forest, CA

I?ve been receiving emails regarding the cars, (MBZ S550 n Audi A8), that I?m currently interested in They have been updating me regarding the vehicle.

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.

I needed a vehicle to go fishing with and they had the perfect vehicle available. The vehicle was exactly how I saw it in the pictures. Super easy process thanks Aaron

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.

The response time was really fast, I had received an email back within an hour. I was actually surprised how quick they had contacted me about my inquiry and I would recommend them to a friend

Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Andrew was very good and helpful. Made the whole transaction easier and fast. Completely explained everything.

Excellent comfort and very good truck, it is very functional in every way, both for business and for personal, it can be said that I have the 2.7L Turbo engine and I can move up to 11500Lbs already checked by me

Buying my car was a great experience: Victor was attentive, courteous, and knowledgeable, and great at following up, whether he had an answer or had to ask his manager, Manny, who was also great; as was Oscar and everyone. Thanks!

All the staff was amazing. Especially our sales person Michael Quezada. The facilities were immaculate and just everything about this place made buying a new car an wonderf experience.

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

Prompt responsive has good deals on used vehicles worth a try and buy with them

The Audi Q3 S Line purchased from Audi Fletcher Jones Costa Mesa was my wife’s favorite color, blue. After an introductory text from Austin, I was coordinating an OTD price for the specific stock number. Mo Masadeh (Sales) contacted me and within an afternoon came to an OTD price and scheduled appointment the next day. Mo was amiable to deal with during the whole of our negotiating via text (my preferred contact) and via phone. The sales process was low pressure and professional. In fact, everyone that I dealt with, Collin (Sales Manager) and Peter (Finance) were absolutely professional. I found the vehicle my wife wanted and traveled from the Inland Empire to make my purchase at Audi Fletcher Jones Costa Mesa, so that says something about both my tenacity and the overall professional and amiable experience with this dealership. Thanks to all of you for providing one of the best experiences in car-buying that my family has had in over forty years of car-buying.

Great experience. Simple and easy. Great staff. Definitely would recommend.

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

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

Amazing service! Caring and attentive to my auto requests. Chris was a tremendous help. He was so patient and kind. Go get a car from STG! I have nothing but good things to say about my experience

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.

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!

I had an excellent experience! The staff here are absolutely wonderful—friendly, attentive, and always willing to go the extra mile to ensure a positive experience. Their professionalism and warm demeanor made my visit truly enjoyable. Highly recommend!

Randy at STG auto was amazing and professional. He was able to work with me to get the rate I want and super satisfied. Highly recommended!

Randy was solid, he helped me & my friend the car we wanted. We got a good price and overall the service was excellent there. I would highly recommend coming here for a used car !

Carlos was very helpful and patient with us. He showed sincerity and honesty in his work and towards us. Overall, it was a great experience buying a car in this dealership.
