Excellent service, honest, reliable, and genuinely helpful! I can't say enough good things about my experience with Auto Squad DB in Diamond Bar. From the moment I contacted them, the service was exceptional. I worked directly with the owner, Matt, and he was absolutely great. He was attentive, responsive, professional, and went above and beyond throughout the entire process. When I arrived at the shop, I was greeted with friendly, attentive service right away, and they immediately started the diagnostic on my car. What really stood out to me was how honest and trustworthy they were. They explained exactly what was wrong with my car and what actually needed to be done without trying to upsell me or recommend unnecessary repairs. Everything was explained in a way that I could actually understand, which I really appreciated. And then, of course, I had to make things a little more complicated by losing my key fob! Matt and the team were incredibly patient and went out of their way to help me look for it, search the car, and even help me figure out which locksmith would be the best option. They absolutely did not have to go that far out of their way, but they did- and that meant a lot. They also kept me informed throughout the process with updates by text and phone calls, so I never felt like I was left wondering what was happening with my car. They were always available to answer questions and let me know what I needed to do next. One thing that really confirmed for me that I was dealing with an honest shop was actually overhearing Matt talking with another potential customer. He was completely upfront with them and even explained why he wouldn't recommend doing a particular repair because it would cost too much and wouldn't make sense financially. That told me a lot about the kind of business he runs. He genuinely seems to care about doing what's best for the customer- not just making money. That kind of honesty and customer service is hard to find these days. Auto Squad DB exceeded my expectations, and I would absolutely recommend them to anyone looking for a mechanic they can trust. Friendly, knowledgeable, communicative, honest, and willing to go the extra mile. I'm very glad I found them and will definitely be going back! read more

I recently had the pleasure of getting my 40,000-mile service at Auto Squad, and I have to give a massive shoutout to Matthew for making the entire experience nothing short of exceptional! Matthew's friendly demeanor and professional approach set the tone for what turned out to be the best car service I've ever had. I went in for a comprehensive service, which included an oil change, brake fluid replacement, AC filter swap, and transmission service. Matthew walked me through each step of the process, explaining everything in a way that was easy to understand and reassuring. What really stood out was his attention to detail. He treated my car as if it were his own, ensuring every service was done to perfection. No corners were cut, and he even took the time to give my car a quick inspection to make sure everything else was in top shape. The pricing was super fair and competitive! I was pleasantly surprised by how affordable the service was, especially given the high quality of work. The quality of service was top-notch, but it was Matthew's personal touch that made all the difference. His passion for cars and dedication to his craft are evident in every interaction. I'll definitely be returning for future services and highly recommend him to anyone in need of car care. Thanks, Matthew, for going above and beyond! read more
