Used BMW X3 SUVs for sale near Boulder, CO

I had the best car buying experience of my life. Everyone was friendly and helpful but Evan was hands down the best! Everything was smooth and fast.

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.

No one likes the process of buying a car, but AutoNation Southwest actually made it a pleasant experience for me! Sadie and then Lauren were both awesome to work with, professional, knowledgable about the vehicle (Jeep Wrangler Rubicon) that I was looking for, and they were both able to help me, without any bickering and in-fighting like I have seen at other dealerships. Financing was pretty quick, and the dealership was very accommodating about letting me swap Jeep mods out with the new one I purchased. Like they let me switch my after market 37' wheels, so I could have my wheels on my new Jeep. The entire process was as enjoyable as it can be, I felt heard, taken care of and respected. I will 100% buy a car from AutoNation Southwest again. Even if you have had a bad experience at one of the other AutoNation dealerships (I am talking about you, AutoNation West) give ANSW a try, you will not be disappointed. But ask for Sadie or Lauren...they are rockstars!!

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.

Meritxell was very professional,friendly,give the deal perfect for me , I’m very happy Whith the deal and Meri, I like the dealership.

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.

We worked with Gabriel at EchoPark in Thornton and we got efficient and wonderful help. Plus we got an excellent deal on a quality car!

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.

Had an appointment for regular oil change and check-up. Didn?t wait very long and my same Service Provider, Erin came out to greet me which was nice.

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

Professional from the start and they were not as much pressure as so many other dealers.

BMW X3 an excellent car. I like the performance and enjoy using this luxurious car.🚘 I very much like having all the safety features.I appreciate BMW service.

The guys at Unlimited had just the car I was looking for! As my wife and I approached the car we had our eyes on, we were delighted to see that a dealer had unlocked the car from the remote so we could check it out. Once we were in the car we fell in love with it. As I took it on a test drive I noticed a vibration in the steering and after mentioning it to the team they pulled it into their shop and fixed it on the spot. I am now the happy owner of a Audi A4 Avant Quattro :) Thanks Unlimited for the great experience and a sharp car!

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.

Absolutely satisfied, they are very friendly and very good prices, safe and reliable, thank you.

My wife and I are very pleased with our BMW X3. I am impressed with the performance and the way it handles. I have owned and driven many autos this by far one of the very best.

Gu Kim is fantastic! Th whole Schomp process, you have to experience to believe. In and out with my new used vehicle in 3 hours! No hassle, no pressure. Don’t go anywhere else if you see a vehicle you want, you won’t be disappointed!!

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.

No pressure sent car up from Springs location to make it easier on us, Let us look it over, drive it, never any pressure. Andy and Shana are great Also a great family owned business, no haggling, no hidden costs you need to stop in and check for you next car here!!!

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

Highly recommend working with Andrew as he was easily the best salesman I worked with at all the dealers I went to. Great people down at Mountain Hyundai.

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.

Quick and easy the staff was amazing and lots of car to select from would recommend

The car meets all my needs. Comfortable easy to handle quiet and fun to drive. Plenty of space for carrying everything. Totally love the ride.

Everyone at this dealership is a class act! Great service. Ask for Ed Rivas to be your lead salesman. He will treat you right and take care of your needs. Extremely knowledgeable and responsive!

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,

My experience buying a car from Karen was great! She was very knowledgeable and made the car buying process straightforward.

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.

We had an outstanding experience working with Jadyn during our recent car purchase for our daughter. From the moment we walked into the dealership, she made us feel welcome and at ease. She was incredibly knowledgeable, patient, and genuinely listened to what we were looking for. What stood out most was her honesty—no pressure, no upselling, just straightforward information and helpful guidance. She took the time to explain all the features, answered every question clearly, and made sure we felt confident in our decision. The entire process was smooth and stress-free thanks to her professionalism and very friendly personality. We left the dealership with a car we love and the feeling that we’d been taken care of by someone who truly values us. We highly recommend Jadyn to anyone looking for a great car-buying experience. She’s exceptional!

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.

Ibe had my car for almost 4 years I got it in highschool it is my first was got 2011 BMW X3 228i x-drive had 120k on it when I got it and now was 193k. I had no major issues besides replacing the coolant tank which was a quick fix and one of the gasket covers regular maintenance is just expensive but you know that before you buy. Great first car and super safe and reliable.

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.

Tons of options in great shape. Whether you're shopping for something newer or more budget-conscious, the lot was well-stocked and well-organized.

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

I had the most incredible experience at BMW of Denver! They treated me like royalty seriously, I was in and out in just 30 minutes! I was a bit terrified of negotiating, on my own, but BMW of Denver took great care of me.I LOVE MY BMW Thank you so much Ed Freehart is incredible and runs an amazing team. Mike Demers in sales was so kind and had everything ready to go for me bow and all. Customer for life!

Our salesman, Jonathan is a true professional. The dealership made this a painful experience. Never going back. The only reason we put up with 2 days of getting jerked around was because they were the nearest dealership that had the vehicle we wanted in stock. We'll never return.
