Just moved to Ontario and needed a credible mechanic for both my Z4 and F80, I decided to give this place and try due to a recent coolant leak. Nas team did a great job by explaining the issue, pointing out other things that need to be fixed in the near future and got it done in couple of days. We did run into some coolant light sensor issue after the fix, but Nas's team owned it up and found the sensor issue and fixed it vs giving me the run arounds. I was very satisfied with the results and I can tell they take their craft and customer serious, and willing to do whatever to make sure they walk out happy. So, thank you again for my first experience and keep up the great work! read more

Best Motor Werks - Auto Repair Near Me - Rancho Cucamonga , California

If you own a BMW and want a shop that treats your car like their own, Best Motorwerks in Rancho Cucamonga is the place to go! I recently took my F90-gen M5 in for basic maintenance and spark plug replacement and the service was nothing short of exceptional. From start to finish, the team was professional, knowledgeable, and truly passionate about European cars. They handled everything with precision, ensuring my M5 got exactly what it needed. What really set my visit apart was the owner's personal touch toward the end, they even helped me out with a detail going the extra mile to make sure my car looked and felt its best when I drove away. It's rare to find a shop that combines expert-level service with genuine care for their customers but Best Motor Werks does just that. My car is running smoothly and performing flawlessly and I couldn't be happier with the experience. If you want top-tier BMW care with a personal touch this is the place to go! read more

I have a 2022 BMW M8 gran coupe. I was taking my car to BMW for service. There prices are crazy. So I did my research came across Best Motor Werks. Nas and his tram are amazing. They are at least 50% cheaper than BMW. And they use OEM parts. Nas is very knowledgeable and easy to talk to. I highly recommend coming here. read more

Hands down the best experience I've had with any automotive shop, period. I first came across Best Motor Werks on Instagram a couple years before I even owned my E90 M3. I bought my car and started noticing a few symptoms that clearly needed attention. A buddy of mine recommended I reach out to Nas. When I first called, I asked about a full inspection and told him I was happy to pay for a diagnostic. Instead, Nas offered to knock out the oil change I already needed and give the car a full look-over during that process, saving me money right off the bat without me even asking. We ended up agreeing to tackle the rod bearings, motor mounts, differential bushings, and the oil change. Not only was the turnaround incredibly fast (car was done within the same week), but Nas kept me updated throughout the entire process. He gave honest assessments, answered every single one of my (many) questions with patience, and never once made me feel like a burden. He even found that my oil pan was missing a few bolts, replaced the hardware, re-threaded two, and only charged me for one. No nickel-and-diming, just solid, honest work. It's rare to find someone who is not only incredibly knowledgeable about the platform, but also professional, communicative, and trustworthy. There's still plenty of work my M3 needs, and I can't see myself bringing it anywhere else. If you care about your BMW and want peace of mind, Best Motor Werks is the place. Thank you again, Nas! read more

"I cannot recommend Best Motor Werks enough! I brought in my 535 GT for air suspension repair, and I'm amazed--it honestly runs like it did the day I first got it. They also took care of the rear brakes, and the quality of the work is top-notch. Beyond the technical skill, what really sets this place apart is the atmosphere. The owners and the entire staff are incredibly kind and thoughtful. It's rare to find a shop that combines high-level expertise with such genuine customer care. I've definitely found my go-to mechanic and plan on returning for any future repairs I might need. If you want honest, quality work on your vehicle, this is the place to go!" read more

This review is based solely on my previous attempt to book a service and does not reflect their quality of work--because, unfortunately, we never made it that far (though I genuinely wish we had). I reached out via Yelp looking for a local shop to replace two tires after catching a flat. I got a fairly quick reply from Nasser (I hope I'm spelling that right), who let me know they didn't have the exact tires I was asking for but had some alternatives. No problem--I let him know I was open to other options and asked for a quote. And then... crickets. A couple of weeks passed with no follow-up, so I decided to give them a call. To my surprise, Nasser answered again and immediately recognized my name from the inquiry. He apologized for the lack of response, explaining there had been some technical issues with Yelp's messaging system. I wasn't upset at all--things happen, and he was super nice over the phone. I told him I was still interested and would really appreciate a quote. He said he'd call me back in about 20 minutes with the pricing. And... well, you guessed it--never heard from him again. Look, I totally understand people get busy, but after already waiting weeks, it was disappointing to be left hanging again. Even if Yelp notifications glitched, customer inquiries should be checked regularly to avoid slipping through the cracks. I was genuinely excited to support a local business--especially since I discovered their shop while visiting Magnum Gun Range next door, which I frequent. Instead, I ended up buying a full set of four tires (instead of just two) and some sick new wheels to compliment them elsewhere--and learned to just stick with shops I know are reliable, even if they're farther away. All the "best" to Best Motor Works, but I'll be keeping it moving. read more
