Used BMW X3 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.

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.

They are very professional, and efficient - moving me in, processing and out when dropping my car for service. The only thing I was a tad disappointed with, was the car wash at the end of my service (I always look forward to that little perk) after paying for service, it's a nice perk, and ends the experience with a most positive feel. After mentioning I was excited to see clean car after service, I noted that it was quickly run through the car wash (no wiping of the remaining insect/bird droppings and no wiping inside the car, and no vacuuming of the trunk which really needed it. Other than that, the car seems to be serviced fine.

I think Mercedes can afford to have other options on the coffee machine besides the cheapest black coffee? Besides that everything and everyone is amazing over there, from George, Maria and Igor from service.

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.

The dealership is easy to work with and staffs are helpful and honest. I had a very positive experience with them. this is the 4th car that O bought from this dealership

This is my 2nd BMW after keeping my previous 528 for over a dozen years ! Still going strong but had to change. After test driving a few, came back to BMW... Its like Apple, once you get an iPhone, it is hard to switch ! Bought a CPO, which gives us more time. Nice car. Good power. Have to constantly check the speedometer to ensure we stay within limits ! So silent and smooth... Love it !

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.

The main issue I've had with this car is learning its vast number of controls, some of which are in strange places (such as at the end of the directional signal stalk) and are not clearly marked. The gearshift, for example, is counter-intuitive, and is moved backwards to go forwards, and vice versa-unlike most cars, it doesn't really move and fit into a slot for the appropriate gear. For no fathomable reason, the rear view camera stays on when you then drive forward. The warning system, for a car crossing or a person crossing, is unreliable; for example, if you have the car in reverse, the car hasn't moved yet, but a person walks behind the car, the warning signal does not sound--it only sounds if the car is already moving in reverse (if the pedestrian was walking right behind the car, you already hit him or her). There are also other "features" that make no sense. On the other hand, the car is fun to drive, reasonably powerful, attractive (I think--my wife disagrees), comfortable (except that one feels remarkably many bumps in the road), and quiet.

Professional, friendly, prompt service keeps our favorite car running and me on time! Thank You!

I absolutely love this car. Sleek design, very sharp looking. Drives like a dream. It takes a bit to learn where controls are for dash but, once you got it down, its easy.

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

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.

Robert and Alex were exceptional to deal with and made what could’ve been a difficult situation very pleasant!

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

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 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.

Received an oil change in record time. Had many questions answered about my Chrysler Pacifica. Melody(advisor) was courteous and professional. David(Manager) was knowledgeable and unhurried. Could not have been better.

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.

GREAT OVERALL!!! Omid was super friendly, great customer service skills and very efficient. Although he was the only one there and with clients waiting on him he never made us feel rushed and took his time with each client.

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

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

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

Nice folks, friendly service. Didn't have car i wanted but good experience. Would visit again. Clean facilities and good location. Clean showroom and restrooms. Free coffee and donuts were great

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

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.

I had a really great experience with them and bought my 5th used car here. I plan on buying many used cars from here and definitely recommend! They have great prices and great quality vehicles.

So fun to drive, quick acceleration, has enough room for all your stuff, looks great, gets great gas mileage. Very comfortable for long trips too. Can't go wrong with this car.

Dreaded the thought of coming in but of course sevice manager, Rodney Phelps and the people at Concord Chevolet did't let me down i'm back on the road again and very happy!

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.

It was a good experience they worked with me to get the deal done a good dealership
