This man gets the job done! Super knowledgeable mechanic who knows what he's talking about. Was able to fix the issue with my Subaru crosstrek pretty quickly after a few days. He even fixed the spoiler that I was having trouble staying clipped to my car. Very honest mechanic who did not BS me or tried to up-sale me on some other things I didn't need. Definitely recommend this place and I found my new mechanic for future vehicle issues! read more

Just picked up my Ford Hybrid, saved at lease $2000 compare to Ford dealers in Upland and Ontario Bill is so reliable and fast on the diagnosis, which costs only $129 comparing to Dealer's estimate of $1260. (That's right, the ford dealer wanna charge me $1260 just to diagnosis, not for any repair) It turned out that my car had rodent problem and after re-wiring everything goes back to normal. This is a costly repair but i think the costs are very reasonable. Bill did a great job on cleaning my engine, see pictures by yourself. Highly recommend to anyone in the region. read more

See all

10/10 Wow!! I couldn't be more satisfied and grateful! Bill is very knowledgeable, professional & efficient. I brought my ford explorer to him after several attempts elsewhere, and he was the only one that diagnosed & fixed the issue! I had my car back in 2 days and he is very reasonably priced. I'm not going anywhere else, Now he is stuck with me :) Thank you Bill!!! read more

I stopped by this shop stating that I believed I was leaking manual transmission gear oil. They offered to do a diagnostics for $85. After the diagnostic, they confirmed that I was leaking gear oil, and suggested that I take my car to a transmission shop, because they don't work on transmissions. Perhaps my first question should have been "Do you work on transmissions", because if I had know they didn't, I would have gone to a different shop for a diagnostic. They could have also volunteered that information, but then they wouldn't have gotten my $85. Nice guy, but I felt slightly scammed. read more

Bill has worked on my family cars and I have to say he's the best. He's 100%honest, knowledgeable and best of all he knows his way around engines. I know and trust Bill with my cars. read more

Bill did an exceptional job pinpointing and diagnosing several difficult electrical issues with my vehicle. Most other mechanics would just start recommending changing a bunch of parts, but Bill did his due diligence and testing and validating to find the root cause of the problem. This not only saved me money, but also let me know that he is a top-notch mechanic. I highly recommend his services. read more

I have an EcoBoost engine on my stupid Ford Flex, same BS as an F150, and the boosters shouldn't have failed before 100k miles (!) but they did. This is a hugely expensive problem, Bill's Auto Repair did a great job resolving this issue for less than the dealer. Reviews on Flex forums tell me many dealers and mechanics fail to resolve this properly; Bill's searched our entire system until he found all the broken parts of the booster all the way back in the catalytic converter. Glad we found Bill's. read more

Bill is magic! My 2012 Ford Focus SEL suddenly and unexpectedly stalled while driving on the freeway without any warning or prior indication that something was wrong. I described my experience to Bill and informed him of how my car had been behaving since it stalled - sometimes it would turn on and other times it wouldn't. When it wouldn't turn on, there was also zero power in my vehicle. He asked me to pop open my hood and start the engine. It didn't start. He messed with something underneath the hood, and it started. Not only was he able to get it to start, but he was also able to replicate the exact experience I had when it stalled, and how it had been behaving since it stalled. Bill listened with exceptional care and concern. And, knew what the issue was immediately. Within a few hours of dropping it off, he called me to describe in detail what repairs I needed and their respective costs. I left it overnight and was able to pick it up the following afternoon. His work is exceptional and his communication is nothing less than amazing. He is absolutely fantastic! read more

Bill asked good questions and listened carefully. I think the price I paid (July 2020) was more than fair considering what other places charge. I like these types of mechanics that actually understand cars and don't rely on computer diagnostics alone. read more

What an amazing experience. I recently Purchased a BMW for my son. It was a used vehicle, and with in the first month of owning it we were already having issues. I google search places around me and decided to go with firestone in Costa Mesa. In hindsight it was a horrible decision. We were charged $3000 and they were unable to help. They told me to find another shop. Luckily I discovered Bill's auto repair. Bill gave us phenomenal customer service. He was honest and pointed out all of the issues we were having with the vehicle. He didn't try to overcharge me for any services that I didn't need. Four days later my sons car is running like new and I will never take any of my vehicles to another place. Thank you so much Bill. We will be back again. read more

Bill provides high quality service at a fair price. I've needed several major repairs on different cars, and his prices were 30% below what Pep Boys quoted me with the exact same service warranty. His turn around times are fast. He is also very honest about whether a service is necessary or not. I highly recommend Bill's Auto. read more

I came into Bill's shop with my 2013 Kia Optima for an engine flush and service and my 2003 Ford Ranger for an oil change and man have I never had any better service than here. Bill is honest and straight forward. He explains every step of the way so you know you're not getting ripped off. I highly recommend Bill to anyone reading this review and I will be recommending him to anyone in need of car service. read more

Bill is outstanding, talented, and honest. We brought in our 1989 Ford e250 after hearing from multiple mechanics that our vehicle was too old for them to work on. Called Bill and he said he would take a look at our van right away. We needed a check engine light inspection, and Bill came through! He was honest about the inspection, physically showed us the codes on his reader, explained to us the meaning of the codes and the issues regarding them. Bill clearly explained how he would assess the problem, he showed us what parts might be needed, and gave us honest, good prices. Bill did not try to rip us off, and he even told us how we could save more money in regards to labor. He gave us an amazing price, fixed our check engine light issue in a timely manner, and gave us honest service. We recommend Bill's, especially if you own an older Ford. Bill is definitely our go to mechanic now! read more

Great service! Bill took care of my car after I've been having recurring issues with the battery on my Ford Mustang. Recommend!

My family had been coming here for years now and this was my first more personal interaction . We ran a engine swap on my 2002 sc430. I am satisfied with how stringent he was about doing things right . If you're not cheap and want to find a good old school mechanic, this is your stop read more

Good honest guy.. Gave me a good deal on my brakes and sensors.. Pricing for my BMW was about $150 everywhere else and he also took a scratch out of my car for free when i didn't ask for it . He goes above and beyond for his customers. He also helped my fiancé out years ago and gave her excellent service as well. He also fixes my mom and dads cars as well and a lot of important peoples cars in inland empire! read more

I have taken my car to many foreign car repair shops. I have had no one who would even take the time to look at my car to see if they could fix it. Bill greater me when I walked into his shop. He took the time to listen to my concerns. Checked it out for me, explained he would need to keep it over night. This gentlemen was very understanding. He quoted me price explained everything that he would do. He is one of the most knowledgeable and honest mechanics I have come across. He stood by his word as far as price. I highly recommend Bills Auto Repair. Maria Sapienza read more

A wonderful small local business that really takes care of it's customers. You feel you are being dealt by one of the few really honest local community businesses left in the area. Long may they survive and service our community. Fair pricing, honest advice and good service. read more

It was my worst nightmare... car shuts down on the 10 fwy in the fast lane. Yes it really did happen. I indeed lived to tell, freeway patrol got me to safety; tow guy however wanted 800 to get me back to my mechanic in LA county... Seriously?!? Highway Patrole officer tells me he has a "guy" not far from there that he's been going to for over 8 years... That "guy" was Bill. Super nice - seriously knows his cars.. very quick repair, and very fare pricing... Car is back on the road & running beautifully. If I lived in Rancho Cucamonga.. he'd be my 'guy'!! (mechanic... okay?!?) If you live in that area, he's the real deal folks - worthy of your business. .... and if the Highway patrole officer who reffered me reads this... I didn't get your name (I was a bit in shock mode) Thank you! seriously awesome referral!! read more

If you want an honest mechanic go see Bill! I went to 2 other shops that wanted to charge me for different things that were supposedly wrong with my car. Bill walked me through what he was doing, how he evaluated the issues and was specific that he doesn't want to charge me for something that is not needed. Great guy, great service and my car is repaired for a fraction of what the other shops quoted me. I will be recommending Bill to anyone I know that needs help with their vehicle! read more

I retract my last post this guy tried to charge me 20 dollars more than what he originally charged me to check it out again for the same problem after i told him that he charged me last time he said he didnt want to do the work i had to go somewhere else read more

Bill Saved My Car I changed my spark plugs on 2004 Lincoln Navigator. When I got to the last rear spark plug, it felt empty. We looked in with a camera and saw something was in there, assumed it was a broken spark plug since these engines are known for plugs breaking off. Bill said he can check it out, brought it in. He quickly found that the plug was in there intact, BUT sitting lower then is should be. For some reason they tried "rethreading" the cylinder and went too deep leaving nothing to grip when trying to remove. He said well at least its working, just have to hope it lasts, cause when it goes out I will know and its not going to be good. To fix it would cost THOUSANDS... So he said he was going to clean up and put everything back together... Few minutes later he calls me. Says he sprayed his air gun in to clean and a black tubing shoot out. He warned that when he removed it there might be a chance it was holding/concealing something bad. But that it was hanging out the spark plug seem so he had to remove, and that it might raise it up to get to spark plug. A few minutes later he came back with the plug in hand, fully intact. The UNREACHABLE plug was reached thru some miracle. He replaced it to the right torque and said we got really lucky, plug was sitting fine and car should be fine. After he assessed the cars suspension, hoses, fluid levels. Explained alot of simple tests, what to listen for, made me feel very comfortable and confident in his knowledge of these cars(lincolns basically a ford). Only man I would trust with my car after this experience. Honesty and knowledge, what more can you ask for from a mechanic. Price was also reasonable. NOTE- brought the car in on a saturday morning, diagnosed, repaired, and did inspection, and i was home by noon. read more

Had my timing belt replaced last month and I received a call following up on his work to make sure i was happy with the work. He did a great job and i was surprised that the price was more competitive than other shops the area. Great customer service and great prices. Thanks bill. read more

I was really hesitant on actually going to a mechanic because all of the horror stories I hear from people but one friend referred me to Bill and I couldn't be happier. This guy is so honest and straightforward and that's all I look for in people! Not once had he tried to pressure me into buying anything or do some unnecessary repair. You got my S2000 running again and you're the only person that will be fixing it going forward! You're the man, see you in 3,000 for my next oil change! read more
