Used GMC cars for sale near Marin City, CA under $100,000

Alexander was an amazing car sales rep. Just the best and so polite and very engaging. He knows his cars! We would absolutely buy a car again from him. He helped us from initial call to the end of the purchase. It was so easy and fun to purchase the car thru him. A million thx again, A!!

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.

BEST AUTO DEALER IN ALAMEDA & ALL OF BAY AREA! My daughter recently purchased her first car & Alex made the experience so seamless! She was referred to Diamond Auto Sales by two friends who had bought their cars from Alex. They highly recommended him. I usually dread the car buying process but Alex completely changed my views. He was honest, friendly, thoughtful, funny, and very knowledgable. You can tell he takes pride in each car he has available. He didn't pressure my daughter at all and once she decided to buy it, everything went so smooth. I highly recommend Alex and Diamond Auto Sales! Thank you so much Alex! I will definetly be back when my son gets his license and when I finally decide to treat myself to a new car. In the meantime I will be recommending them to all my friends & family. Thank you Alex and team! We are so grateful.

Awesome car! Reliable and I have 200,000 miles on mine and never had a major repair. Comfortable. Good for towing. Easy to hold a lot of people. Speaker quality is good. I’ve owned about 6 different cars and this is my favorite by far.

These guys are awesome the hooked me up and kept everything in my price range I'll have to go see them when it's time for a new vehicle! Without a doubt! Greg is awesome no pressures no hassle, good guy! The GM is cool too!

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.

Review for service. Reliable, good communications through their messaging app. Wish service advisors could be a touch warmer and authentic with customers. Bonus would be more promotions for regular customers, but even without that, overall good place to get car serviced.

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.

Great team to work with. From the very first contact they were very helpful and made the process easy. Michael was great and Byron was fun to work. Highly recommend!

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

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.

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.

Though I did not buy a car there I had a good experience. Vlad was really helpful and great in helping me and showing me the car. I would recommend this dealership.

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.

Sammy and Conni are the best this is our second car. We always get the red carpet treatment Sammy gets it done and Conni well the most attentive sales person I have ever met. They don’t push you to buy, I can’t say enough about this place!! Love it and will shop there again and again.

This truck is exactly what I was looking for! Very well kept and in great condition. Great ride and interior is like new for this 2013 Yukon. All the comfort and space I was looking for to get ready for the winter!

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.

Very straight forward (which is a good thing) Had the exact items I was looking for. Matched my best price. They worked with me on my pickup schedule as I bought multiple units)

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 bought two cars and sold four cars through these guys. One of the best smaller, specialty and high-end car dealerships you can do business with IMO. Quality cars that are sold by honest guys with integrity. I mean that. The owner cares about running an honest business. There are so many other fly by night and sketchy shops you can deal with and this is not one of them. I trust these guys whole heartedly and they will always get my business where possible. They also can do awesome wraps, PPF, etc. They have a great services team as well. Highly recommended.

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 wait took a little longer than I was told, but the service was good.

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.

Bought a used car from Stewart the whole process was made so easy! I will absolutely be buying my next car here too!

I just bought a GR Corolla from Jae and he was very communicative during the process.

Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

Ellos son muy amables, el proceso fue r�pido, y te dieron opciones para poder sacar un buen interes. Sin duda es un buen dealer y lo recomiendo

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.

I?m very happy with the car and glad I decided to go electric. I wouldn?t feel as confident in my choice without the support and professionalism that I received throughout the process. Angelique provided excellent service!

I love my 2018 GMC Acadia just wished windows were tinted and had a tv for kids and grandkids overall I have had this truck for 2 years and I Love it and use it for family drives cuz of how much room it has I have even used it for work meetings and we all travel to the meeting together .

Service personnel are very helpful. They informed me of the progress of repairs. They have offered me free car washes. The repairs were done in a timely manner.

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.

To be honest, this SUV impressed me with the great performance even with the small 1.5 liter engine, and huge space inside, it rides like a bigger vehicle, very responsive on the highway and very quiet cabin. My wife really liked it.

Id like to express my hear-felt thanks for excellent service Andrea Mello provided me with the maintenance of my Toyota TDR 2017 Toyota Tacoma. I have learned through the years not all agents are created the same. I was highly impressed with Andrea's customer service , professionalism, and capacity to explain what was needed for my truck. She was honest, fast-hardworking and proved to me confidence that their is no task that is to large for her and her crew. I was extremely happy with her quality of service. I intend to continue our relationship with Toyota in the future and looking forward to seeing Andrea Mello again. I whole hearty will recommend any one who is seeking first rate customer service to Toyota and Andrea Mello. Thank you, Sincerely, Yvette Thoma
