Our story
PC Auto Repair is a small Rancho Cucamonga shop where the owner, Quan, is also the mechanic working under your hood. When customers need help, he explains what the car actually needs before he touches it, and he prices the job fairly instead of padding the bill.
Our customers stick around for years because they know who is doing the work and can trust what they are told. One family drove past their old shop, saw the doors closed, and Quan walked over himself to help. That is the kind of shop we run.
We handle everything from routine maintenance and smog checks to suspension work and engine repair, and we treat every car, whether it is a daily driver or a project build, with the same care.
What customers say
“We were so sad when we saw that Al's was no longer open since she had been going to him for around 30 years. My husband and I had no idea where to go next but thankfully we came across PC Auto repair because of its owner, Quan, who came out to check on us since we were across the parking lot. Quan was super great and very nice. He took a look at the van, did a great job explaining what needed to be done, and he gave us a great deal. The van, which is a 98, passed the smog thanks to Quan's help.”
“Been going here for over 5 years now. They have been there for me in many situations. Sometimes they would check my car out for free. Their labor is the cheapest I've seen in my opinion, and the quality of their work is excellent. My wife and I have been happy with their service and continue to go there for maintenance and service. I highly recommend this place.”
“My car's CV and ball joints broke on my only car at noon and I had to be at work that night at 8:00. I had my car towed to PC Auto and Quan not only had my car fixed and ready for me so that I didn't have to miss a night of work, but he also did it at a great price that didn't break the bank. Quan is the best mechanic, he knows his cars. Very honest and reliable.”
