Used INFINITI cars for sale near Concord, CA

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.

Comfort, power, space, looks - the Infiniti GX80 has it all for my family. We needed space and we got it. Infiniti added style and comfort. I'm very happy with this vehicle - both on the highway and around town.

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.

Bought this vehicle in 2014 and started having minor problems but due to wear and tear,but had an major accident and even no one got hurt due to support bar . But no air bags deployed . Very concerned.

I loved the no hassle and great price on warranties. I would recommend CarMax to everyone.

After spending time with the 2024 QX80 Sensory, I’m comfortable giving it a five‑star rating—not because it’s perfect, but because of how well it delivers on the things that actually matter in this segment, especially at the cheaper real‑world transaction prices these typically sell for. The build quality stands out immediately. Material quality, fit, and finish are all genuinely impressive, and even after 30,000 miles the cabin remains tight with very few creaks or rattles. That’s something I can’t say about several other luxury brands I’ve owned, including BMW, Mercedes, and Cadillac, which tend to develop interior noises far earlier. On the road, the QX80 excels at what it’s built for. The ride is extremely comfortable, highway noise is well controlled, and the 400‑hp V8 provides smooth, effortless power. It’s a relaxed, confident cruiser that makes long family trips easy. The interior is spacious, the leather is high‑quality, and both the interior and exterior design have a clean, upscale look. Fuel economy is average for a large V8 SUV—nothing surprising there. The real drawbacks come from the dated technology. The infotainment system feels behind the times, and features like a head‑up display or massaging seats simply aren’t available. The front seats could also use more side bolstering for better support. Even with those shortcomings, the overall package is strong. When you factor in the typical selling price—often well below MSRP—the value becomes even clearer. You’re getting a large, comfortable, powerful, and well‑built luxury SUV that prioritizes reliability and long‑term durability over chasing trends. It’s not perfect, but nothing in this class is. What the QX80 does, it does exceptionally well, and that’s why it earns a full five stars from me.

I came to this car from a 2016 Yukon which was a rolling dumpster fire. At 102k miles, I haven’t had a single failure with this car. It tows extremely well, the seat comfort is by far the best I’ve ever owned, I don’t love the exterior styling, but its such a great owner experience that it doesn’t matter. Maintenance is like owning a Camry, cheap and infrequent. AWD system makes driving in all conditions a breeze. Great vehicle.

I was recommended to try Concord Nissan from a colleague, instead of the other Nissan dealership I normally deal with. I was referred to Deven. He was EXCEPTIONAL 🤩🤩🤩🤩🤩, by this I mean I felt like he went above and beyond. Not one time did I feel pressured into buying a vehicle. Truthfully, I bought the vehicle because I was treated nicely, respectfully, and that my business is appreciated, because I did stop somewhere else first and ended up leaving because nobody came to even assist me. Deven's customer service and a great car 🤩🤩🤩🤩🤩🤩🤩🤩🤩🤩. I will ALWAYS recommend to go see Deven first, save you time, money, and have you driving today. 😊

I have a 2023 brand new off show room floor an my windshield has been leaking water from outside when it rains extremely hard outside had to take it back within 1 month of having it an they kept it for 70 + they replaced the windshield only for it to happen this year again this is not a good look for infiniti the service department say my car is the 5th car to have issues with water leaking from windshield

I recently purchased a used car at this dealership. I came in with fairly low expectations and was pleasantly surprised! There were several options for low budget used cars, however they were still excellent quality. Thank you David!

Narrowed to three finalists and the QX60 was head and shoulders above the competition. Price was also higher but the difference seemed to justify the INFINITY. On the highway it is a pleasure.

I would give them 10 stars if I could. I have purchased 2 vehicles from this location and have my entire family shopping here! Great service and follow up! Great used cars here! My family and I will shop for out vehicles here from now on!

This is my second Infiniti. I still own my 1st one which presently has 312,500 plus mile. It was very reliable. I wanted a vehicle that had everything I wanted in it. So, I purchased it. I love it is all I can say.

Have bought multiple cars and trucks from here vehicles have always been good staff is friendly. Will always recommend them to family and friends. Love that there's no salesmen and no pressure.

I've had this vehicle for 2 years and I love it. Such a smooth ride for a large SUV. Beautiful on the outside and inside. No mechanical issues whatsoever so far and i'm at 90k miles

Michelle was very sweet and shared a lot of useful information about the car! Sales Manager & Finance made great conversation and helped a ton as well!

I purchased this car last year I can say it is best car I ever owned, it is true the interior not like German but, when you drive it you forget about interior since i purchased no issue I drove 3000 miles monthly it is made for motorway comfortable with high tourqe offer strong performence I prefer qx70 over bmw and, mercedes

I recently bought a new 2022 Tiguan. Best SUV I could have ever purchased. it was great right when i walked into the show room with my trade and buying my new car. it was an easy smooth process from John the salesman and Eddie from finance made everything easy to understand and drive off with my new car.

Love the body design, the interior is comfortable. However the technology could be more updated. Car is very reliable it does 26 GPM on the highway, engine is very powerful.

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.

Beautiful car inside and out! Lots of leg room in the back. Low miles , luxury drive Black leather interior and tinted windows As all the bells and whistles

I had a great car buying experience. I would definitely come back. The team was very helpful and made the experience a good one. I highly recommend this car max location and the people who work there.

Awesome Q60 Red Sport 400. The dual informational center needs a serious upgrade. Needs better exhaust sound especially on the red sport 400. Overall I give the red sport 4.5 out of 5.

The Infinity is an excellent, & safe vehicle. I brought both of my infinity's from SW infiniti. The staff are honest, knowledgeable, & professional, also friendly.

We went in on Saturday 8/26/23 to look at a used vehicle. Jakelin greeted us upon entering the sales office and quickly provided us with her assistance. Once we informed Jakelin which vehicle we were interested in she provided us with the pertinent background of the vehicle. She then brought the car to us and accompanied us on a test drive. We ultimately purchased the vehicle. Jakelin then sat in the vehicle and reviewed all the vehicle’s features with us. She then provided us with her business card abusing us to contact her with any questions we may have. Thank you Jakelin for a great car buying experience!!!

Excellent power, beautiful lines, great reliability... what else do you need? I'd buy this car again if given the choice. Infiniti hits it out of the park with the Q60.

Drives and handles very well on the road. The only surprise was during purchase. I expected it to have a Bose sound system like my G35 had, and the automatic front seat and steering column. On my G35 these two systems moved in unison and had memory for the position of the seat and steering column that could be set for two different drivers. The only other thing is the absence of a spare tire. Those run flat tires ride very hard and are not cost effective for owners.

So far so good...Still getting to know my new car. Will be driving it around town and can really see the ride. Wish my trunk space was a little bit larger...

The Diamond Auto staff were incredibly helpful, informative, efficient and honest with my purchase. I would absolutely do business with them in the future.

I owned this car for 7 years and drove it 131,000 miles with no major problems. I loved the design, power, performance, and comfort. The AWD was awesome in rain and snow. Only way to improve the vehicle would be to improve the gas mileage or at least make it run on regular not premium gas. It was the most amazing car I ever owned until I was rear ended and it was totaled. It took the hit like a champ though. Solid car. Probably saved my life.

First time buying a luxury car. Nice and will enjoy it! Will enjoy it. Thanks. I look forward to driving it for years to come. Black luxury

Is good reliable luxury car.Little expensive on gas as is need premium and in city 16.4 gallon/100miles.Perhaps not suitable for daily driving to work?Unless you don’t count every penny.

Just an update on my first review when I purchased the vehicle we could not find the special lock for the wheel lug nuts which were custom,The owner of the truck prior to me could not Find it so Marin imports paid to have my local tire shop replace whatever needed to be replaced which luckily they had a lock that fit it. The process was very easy and painless thanks again Marin imports.

Only had this QX55 for a few days, so cannot comment on reliability yet. Very high quality fits and finishes. Interior is very high end with real leather, carbon fiber, sensible instrumentation, peppy engine, very quiet and smooth ride, despite having run flat tires. Quality of paintwork is excellent, white tricoat is really eye catching, wheel finish is well done. This Essential model is a bit pricey compared to the Luxe model, but does have several nice extras. We traded in our 2016 Infiniti QX50, which was super reliable; so hoping for the best.
