Used BMW X3 for sale near Foster City, CA under $20,000

I purchased a 2024 Mercedes G Wagon 63 AMG from Steel Chariot in January 2025, and the entire experience was fantastic. Nima, the owner, personally helped me with the purchase and went above and beyond to make sure all my questions were answered. He was knowledgeable, professional, and genuinely cared about making the process smooth and transparent. The dealership had a great selection of high-end cars—plenty of impressive options to choose from. The customer service was top-tier, and I never felt rushed or pressured. If you're looking for a luxury vehicle and want to deal with honest, helpful people, I highly recommend Steel Chariot. Thanks again, Nima and the team, for helping me find my dream car!

This Truck is a replacement for 2008 LR HSE (totaled) I just got it over a month ago and it is good so far. Very fun( zippy) to drive. Wish the seats were more comfortable. I have the 35i XLine. 79k on the clock. You have to get familiar with the idrive, also my heads-up display is not working properly. There is also a coolant leak which will be taken care of under warranty. This vehicle also used premium gas. Soo far we will see how reliable it shall be.

Ahn was very helpful and referred me to Samson. He made financing my car very easy was in and out of dealership! Would definitely be returning and referring people! I don't know what the bad reviews were about I was in and out with a new car in less than 2 hours. Thanks again guys!

I cannot believe that BMW put a 4 cylinder with turbo in an X3. It is the single problem I have with my car. otherwise it is perfect. The 6 cylinder in my 2005 was Awesome!!!!! BMW stands for Performance, GIVE IT.

I had a very easy, no pressure experience. We bought two cars from them and traded one in.

I have used the 2019 BMW X3 for over a year now, as my third BMW, the other two being the 3 series sedan, with just one problem; Fuel pump failure, though due to my negligence. I now understand that the BMW cannot be operated without sufficient Fuel.

I bought a 2022 Mercedes GLE 450 from Steel Chariot in February 2025, and I couldn’t be happier with the experience. Nima, the owner, was incredibly helpful throughout the entire process. He took the time to answer all my questions and made sure I felt confident every step of the way. The dealership has a big selection of quality cars, and their service was top-notch from start to finish. No pressure, no hassle—just honest, straightforward help. If you're in the market for a luxury vehicle and want great customer care, I highly recommend checking out Steel Chariot. Thanks again, Nima!

This vehicle has has taken my wife and me cross-country, as well as several other long distance trips, with a sum total of only one flat tire and no other mechanical, nor electrical issues at all! Any repairs have been moderate and frankly expected given the high number of miles (150,000 so far) on it. I expect to keep it for another year and a half.

Mansour was super helpful, friendly, and knowledgeable. He was very attentive and walked us through the entire process. And he has also been very responsive on follow up questions and issues.

I am new to BMW and so far I am loving it, especially the way it handles the road and the overall comfort of the car

Make sure you ask for Mansour. He is the best! Very knowledgeable and makes sure to answer any question you might have. You will be glad you did. Very fair on price.

Our 2016 works flawlessly! We are so pleased we just purchased a very low mileage one with $15,000 in options which should make this one even more pleasurable,

I had a good experience purchasing a used car at BMW Fremont. The sales rep, Calvin responded to my questions very quickly. There were some issues with the car and Max assisted with arranging the Servicing Dept and fixed the problem. However, after purchasing the car, I did realize the trunk cover is missing and the dealer told me they were not able to find it. That?s the only thing I felt disappointed in since the trunk cover is useful in securing the belongings in the trunk.

Six cylinder turbo provides great performance. Sport package worth every penny for the handling. I had a 2011 E90 several years ago with the same N55 motor and Sport package. This is just as much fun.

Very nice experience I would definitely come back and do it again. People very friendly and helpful. They explained a lot about the car I bought.

I had this car for several years. In that time, it was a great car. The only downside to the car was the fact that it was a BMW, so I couldn't take it to any old mechanic shop to get the oil changed. The car has great pickup and breaking, and is great for long distance rides. It's a smaller SUV, but there's still plenty of room. And when I got into an accident, it functioned correctly and kept me and other safe. The airbags deployed like they were supposed to. The only reason I ever got rid of this car was because it was totaled.

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 it for my daughter. Wanted a safe, reliable vehicle. It has not disappointed. I drive it more than she does. Plenty of pep and great pickup. Blind spot and lane departure warning are a huge plus. Only downside, the seats are not terribly comfortable.

Although I was not able to come to a deal on a Tesla Model X the gentleman I spoke with (Scott) was extremely helpful and very nice. He was respectful and straight up with me about everything. I would definitely deal with him if I end up buying a car there.

Its so comfortable, fast, sport, low mileage, so clean . It is 2013 with 67k mileage, honestly so clean look like new car .new tire and full service

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

Great car, has over 70k miles and no major problems. With the Diesel engine I get great MPG, almost 40 on highway trips, over 500 miles per tank.

It was my best experience, Very fast and easy. There was a sales lady she was really helpful.

Husband has wanted a BMW since the 1980’s. Other priorities in life happened, so there you go. Fast forward to August 2020. Time to trade in the tired 2012 Ford Escape. Dealership has a 2014 BMW X3 25i in blue water metallic. Sold! Comfortable, QUICK!, with navigation, parking sensors/backup camera, heated steering wheel, etc. This is a gas sipper considering it takes premium fuel. Not a fan of the brake dust that turns the beautiful front wheels black, but we just keep up with cleaning them. So far so good. Seems to be reliable so far despite the reviews on the exorbitant maintenance costs German cars incur “when they get older”. This will be driven by retired husband about 2-3 times a week, so hopefully it will treat us well on maintenance costs. Bought a one owner, 72,000 miles, regular maintenance performed BMW, and to be honest, it’s not just husband that loves it!😀 Documented)

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!

The Supreme driving machine ! I'm 60 years old I have been driving since I'm 19.many cars ..Superior handling ! Comfort ! Even on rough roads SMOOTH ALWAYS .CANNOT BEAT THE DRIVING MODES .

For people like me Problems with neck upper back not having to look down on speed or navigation ...makes driving less painful ...don't drive much anyway but does help when I have to go.alone

The sales manager contacted me within a couple of hours. He invited me to come down for a test. Unfortunately I haven’t been able to meet the him. He has reached out since our first emails and he has been very professional. I appreciate his patience. I will try and meet him and test the BMW as soon as I can.

This car met all my needs. Comfortable, roomy, classy,sporty and much more than expected. After purchasing the 430i I switched to the x3 best decision I ever made....

I want to commend Saeed and the other staff who helped me purchase and stand behind the 2015 JEEP Wrangler I bought in September. They were accessible when I needed their help and on my side when I had a problem with getting repairs covered by a 3rd Party repairs warranty I purchased.

I think this car is a good family car to drive around with since it has the key features needed to be a family car

one of the best purchases i have made, all the staff was friendly and helpful have also checked in to see how my new ride is driving. I did look at another BMW dealership and were not helpful but more of a pain between all the calls and text messages, I'm VERY GLAD I purchased my 2026 X5 BMW from BMW of Mountain View.

My second X3 and love it more than the first!I especially like driving in the sport mode. Great feel and ride and the gas mileage stays about the same.

I recently purchased a 2025 Volvo XC from AutoNation Volvo Cars San Jose, I couldn't be happier with my experience! From start to finish, the entire process was smooth, transparent, and professional. The XC 60 is an absolute pleasure to drive elegant design and comfortable interior, impressive safety and tech feature. A big thanks to the AutoNation San Jose team for their excellent service and patience throughout the purchase process.

STAR AUTO MALL: Worst car dealer EVER! I bought a 2017 BMW X3. They never checked the car! I had problems immediately! I called, emailed & texted... Star Auto Mall would NOT return my calls, texts or emails! I went to BMW dealer, and they found lots of issues! Wires hanging down, tires rubbing, etc. It cost me $480 to fix it! I billed Star Auto Mall, and it looks like they're just chucking me the finger!! AVOID these incompetent thieves! Here's links to my issues with the car they sold me! https://thebassplayer.com/BMW-Bill.pdf https://thebassplayer.com/BMW-1.mp4 If I don't get a check by the end of the month, a lawyer friend told me it's a slam dunk in small claims count.
