Used BMW X3 SUVs for sale near Castro Valley, CA

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've had the 2025 X3 30 now for 5 months and it is great! It replaces our 2022 X3 that was recently totaled and both passenger walked away with just bruises so it is a safe car! This is one reason I purchased another X3. Big difference on the interior panel than the 2022 as everything has gone to touch screen for all controls which I not real fond about, even the owners manual is on the touchscreen software, The twin turbo gives plenty of power and the gas milage has improved from the older model. The gears change smoothly and the ride is also smooth. You now get a spare tire since BMW did away with the run flat tires which I hated as they did not wear great. The accessories offered in their package covers everything you want in an auto. I don't understand why the rear exhaust are hidden though as I like the chrome exhaust on my old 2022. This year the 3 was redesigned and it is slightly bigger.

Always a positive experience. I am offered transportation home or to other location, if needed. My service advisor is attentive, accessible and updates me on status of car repair. His recommendations are clear and will tell me if needed at time of service or if may be done in the near future. I do to feel like he is trying to upsell anything.

Love it. Car is comfy, quick and the wonderful B58 Twin-Scroll Turbo I6 makes all the right noises! Awesome daily driver. Period! Interior has all of the amenities you could ever ask for. Ride is luxury-oriented but also can grip & RIP through the corners, almost as well as any sports sedan out there pretty much.

Great buying experience never felt pressure they took my budget seriously and worked to get me what I asked for. I would buy from here again and I think I will for my next car and will recommend to anyone looking to purchase a car.

I love this car I bought it for my wife for her Birthday and she just loves it. The ride is great and all the extras it has it perfect

It was the most pleasant experience the customer service that they provided was amazing. They have the patients they?re willing to take out cars for you. Let you see them try them with your family, and I would recommend the dealership to my family and friends.

Only have been driving the car for a week, but it is clearly the best SUV I have experienced. My wife drives the Mercedes 300 - a fine car as well, but I have always preferred BMY engine performance and handling. The X3 is simply a pleasure to drive.

I WENT TO THE DEALERSHIP TO PURCHASE A MINI COOPER S CONVERTIBLE IN THE COLOR I WANTED THAT WAS AVAILABLE THERE. THE FACILITY AND STAFF WERE HELPFUL, COURTEOUS, AND ACCOMMODATING. I WAS ABLE TO TAKE THE CAR HOME ON THE SAME DAY.

This vehicle was very fun to drive, it is comfortable and sporty, and the handling was excellent. Barely any issues, just overall a great driving experience.

Look around first so you understand that their prices can't be haggled but it is worth it. I couldn't find a single car within $1K of their price. And the quality of the car was outstanding. Easy. Great kid's corner keeps them occupied too. No pressure sales is a beautiful thing.

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 recently had my car repaired at BMW of San Rafel and was very pleased with the support and personal attention from Tim - my SERVICE ADVISOR

It's all about the B58 in the M40i. I dinged it one star on comfort because this little SUV rides quite "sporty" even in Comfort mode. I absolutely love this about the car, but I could see how some would feel this is too harsh as it is not a luxurious, cushy ride. But tuck this little beast into a fast corner and it's just...wow! This little German SUV is a sleeper. While the X3M is very nice, the M40i is the perfect balance in my opinion. BMW has really stepped up their game in the X3.

Straightforward & fast. Anthony Guerra was super helpful & friendly. We asked for a ‘deal’ and he made it happen. I’ve bought 4 cars from various lots & this was the best experience yet.

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.

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

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.

I had a great experience with Paul. He was efficient and easy to work with.

I had no choice, my car of 20 years, which I bought brand new in 1999 was done. With so many websites ( I looked at several), I was not sure where to go. Then someone mentioned Car Max to me. I looked on line and saw a few cars I was interested in. The next weekend I drove to Colma to checked out and test drive a couple of cars. I decided to ask about Hybrids...you had 2. I test drove one of them and could not resist. I bought it. I was very impressed with the buying process. It was quick, easy and believe it or not relaxing since the sales person completed the paper work for me. Yes, I had to sign several sheets but that was a given. Something I was dreading for the past two years, was so surprisingly easy I couldn't believe it!!!

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.

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

The experience was easy and fast they were not pushy and not trying to sell a different car the sales man was friendly and very helpful and did what he could to make it easy and fast to get out of there

Great car love bmw very reliable never had any mechanical problems great in the deep snow Excellent acceleration Handles and drives like a sport score

We were definitely nervous about going to a used car dealership, but David was great. He was patient with us as we thoroughly inspected the van we eventually purchased, really fair with the price, efficient with the paperwork, and even surprised us by paying for the car's next year of registration. We've had the van for a few months now and have driven it on two road trips (600 and 2500 miles, respectively) with no problems!

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)

Richie the mechanic is the best! He took the time to figure out what the problem of my car was! Oil change and changing the damage wire within 1 hour and half amazing !! Other dodge dealership took 3-6 hours to tell me they couldn’t find anything wrong. Definitely recommend him !!!

The X3 m40i is the best family vehicle. Got a decent deal from CarMax on a lightly used 2019 x3 m40i. The hk sound system sounds terrible unless you figure out how to turn off the exhaust sound that comes through the speakers (leaves little bass balance left for the music), but luckily there are a few tricks (check forums). The vehicle is a blast to drive, yet can carry the whole family and luggage anywhere. I had a few e36 m3's a while back and repairs were reasonable and easy to do a lot of stuff independently, so repair costs (only needed brakes, tires and oil in the past 30k miles) on the new BMWs did come as a bit of a shock, but being proactive helps. The vehicle has been super reliable with no mechanical issues.

Very responsive to my inquiry, both via phone and other media. I ended up not following up because I found another car elsewhere which I preferred, newer and with lower mileage.

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 love the car and at the same time I can't help to hate it. What I love about the car would be the luxurious interior, comfortable and quiet cabin, smooth ride, ease of access, and a few extra features that were put in as an add-on. What I don't like about this car would be the poor fuel economy for the 30i model, especially when compared to the B-58 engine. Apple carplay connection issues, no option for remote start unless I want to void warranty, and no option for the iDrive Recorder App. Exterior Styling - 8.5/10 Interior Styling - 9/10 Comfort - 9.5/10 Cargo space - 8.5/10 Driving smoothness - 9.5/10 Horsepower - 7/10 Fuel Economy - 3/10 It's been an overall fun car to get around in. It's easy to get in and out of, smooth on bumpy roads, and it is quiet. The fact that only 2022 models and newer offer remote start and iDrive recorder is a big disappointment. But I think my biggest disappointment would be the fuel economy. As I had the B-58 in the past and averaged out 11.5L/100km and in this X3 am averaging 13.5/100km which was worse than my pick up truck. I might not keep this car for long-term just because of how poor the fuel economy is.
