Used BMW M4 for sale near Rancho Cucamonga, CA

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

Luxury and outstanding performance. High quality leather and carbon fiber interior combined with 11.3 second quarter mile, outstanding handling and brakes. Best infotainment I've seen on any car. No other car in this price range matches it.

West Covina Audi was a "Excellent Experience ". I can't express how professional and courteous the entire dealership staff handled the purchasing of my car was.

Haven’t reached break-in mileage limit as yet but so far, car has met all of my expectations with regard to quality and performance. Agree that infotainment display is a bit overwhelming. Front end isn’t as objectionable in person as seen in pictures or videos.

Anthony sold me the 2020 Mazda 6. Super nice and very informative and fast too.

IMO one of the most beautiful cars in and out. Has a stiff ride with great power. Many many control options from stereo to performance. Only drawback is not a lot of interior storage.

Enjoyed my experience here at this dealership. Came out with a brand new car! Anthony was extremely helpful and guided us to find the car we were looking for.

Not built for comfort, built for speed. The CS interior is minimalist. When you slide into it, there’s no question what you are there for. The car will snap your head back and paste you up against the door panel—“Freude am fahren”—form follows function. Like they said of the Spitfire in the Battle of Britain, you don’t sit in it, you wear it.

Love the versatility of this sports car. Track and travel worthy. Comfortably fits larger people. Love the hard top convertible. Carbon ceramic brakes amazing. Trim and paint color very nice. Styling hasn't changed much over 5 years of F83.

Keshan and Hamsa were Great through the whole process fast and quick will definitely buy again

Met all my needs couldn’t be any happier everyone I’ve gave a ride said what a good car very fun to drive very nice to look at I am a race car driver and need a fast car and this meets it

Adam did a nice job locating the vehicle I wanted to see. He went the extra mile tracking down the service manager, beginning the purchasing process, and ultimately ensuring the vehicle was ready for pick-up a week later. I found Adam to genuinely care that I had a good purchasing experience.

Xavier, Sebastian, Aaron, and Nicole were all helpful and good to work with! Thank you!

Kris was great! Had a lot of patience with me and definitely will recommend him for your next car purchase.

Nelson and the rest of the New PBB Auto took care of me and ended up working out a great deal on a 2017 Mercedes Benz C300. Would recommend for a quick and seamless car purchase.

Visited to test drive through Costco Auto program. Monica was prompt in connecting and arranging a test drive. Since she was occupied with a customer, Olya assisted. She was very professional throughout the test drive and purchase of a 330i. Negotiated a fair deal and the following day Olya drove 30mins to our house to sync our phones with the car and demonstrate the digital functions of the car! Great experience from beginning to end

I highly appreciate the professionalism and efficiency at STG Auto Group. Maria made sure I was accommodated throughout the whole process. She was polite and always elaborated when I had questions. I’d highly recommend going to STG Auto Group for your next vehicle purchase. Ask for Maria, she made it easy.

It was such an amazing experience I totally recommend Luiz was super helpful and very nice!

Great experience and specially the treatment by Ali Khan and team. They made the car buying experience a pleasure. Nikesh and Zohayr were great too. This place is amazing and I will be recommending them to family and friends. Thank you Chino Hills Ford

Love this place , love the service, love how fast my process was to get into my M4 .best dealer I’ve ever made business, super polite , humble and very respectful, they even car washed the vehicle, man come one I was like whatttt!!! Super happy I drove out from Hollywood and I was not disappointed. Check it out for yourself!!!!!!

I’ve owned my M4 since 2016 and enjoyed every drive. I especially look forward to warmer temperatures when I get to drop the top and enjoy open-air driving at its best. This car has been very reliable with a flat tire being the only need for repairs. On the down side, the back seat is way too small for full-size humans. But then, I didn’t buy this car for its people-mover abilities.

The F82 M4 will go down in history! The looks are timeless, so much power, and very reliable. One of the best bang for your buck sports cars. However if you are looking for a comfortable daily driver this is not the car for you. It is stiff and you feel every bump in the road. Not a bad thing but if you want more comfort get a 440i. This car does what it is supposed to do perfectly.

Every time I get in it there is a sense of thrill and the interior is gorgeous absolutely amazing piece of work all the technology is so modern

My online salesman Xavier was great! I live 2,000 miles away, and the whole transaction was done on my phone, and within 24 hours. Having to come up with a shipping company was the hardest part of the process.

So far, which admittedly is only a month and 800 miles, but so far, loving it. Traded in a Cadillac V Series (The true "V" series and prior to the Blackwing V Series) and I find the M4 Competition to offer a slightly more comfortable ride in the softest setting versus the Cadillac and roughly the same handling capabilities in the "sport" settings. Still getting used to BMW's steering though. Just something different with it and maybe once I get used to I'll trust the M4 even more than the Caddy?

Moe was my point of contact and was great through the whole process! No we are just waiting for the registration stuff so the car can be fully registered.

Handling on a curvy road, acceleration on a straight stretch and the sounds of spooling turbos is a real adrenaline rush. This car was so much fun to drive I hate to see it go. Carbon fiber refinements inside and out make this vehicle a real head turner. Looks, handling and brute power, what more can a car enthusiast ask for?

Riverside BMW made getting my new car incredibly easy. Jimmy listened to what I wanted and came back with exactly the car and deal I needed before I even stepped foot in the dealership. The entire process was smooth, fast, and completely stress free. No games, no pressure, just honest communication and great service from start to finish. I never would have imagined I would have a car this beautiful in my driveway. This was truly the best and easiest car buying experience I have ever had. I could not be happier with my new BMW and I highly recommend Jimmy and the team at Riverside BMW. ⭐️⭐️⭐️⭐️⭐️
