    (I had this in my drafts and forgot to post so im posting it now)…read more I usually go to a mechanic in Upland, CA but when my check engine light turned on yesterday while i was here in Whittier i decided to look for a mechanic in this area since im always in Whittier. We went driving around to see what shops we found. Im really big on vibes and so when i spoke to a few mechanics I didn't feel comfortable with them. I wanted a place that wasnt overly expensive but that did a great job. After stopping at a few shops we saw this one and stopped. My first impression was 50's vibe lol Its like a small historic museum with a lot of retro items. The person I spoke to came across as a "no bs" type of guy. I heard him talking to the person in front of me and although I was a bit intimidated I felt that he would be honest and felt a good vibe. He was very professional. The communication was excellent. Service was quick. And they explained what needed to be done in a way I understood. The receipt they give is very detailed which I loved. I have since got a new car but if i ever need a mechanic, i would come here!

I called prior to get a price quote and they said it could be done today. I decided to wait while they did this service. (Btw, Freon is $10 an ounce!) *This is my usual place to come to get a quick oil change too! Price is reasonable and they are open 1/2 day on Saturdays.

    I would like to say this place deserves the name Integrity Automotive…read more My only complaint is I wish they were closer to me. My regular mechanic is close in whittier for regular maintence. But when I had and electrical problem all 4 power windows quit at once on my ford fx4 my guy was like it could cost a 1000.00 I remembered Integrity fixed my son's toyota electrical problems for a great price. So I made the drive expecting 1000.00 When I gave them the problem I was given and estimate of 240.00 . But I was told it would be for 1 1/2 hours of labor to find the problem. If they fixed it sooner it would be less??? Out the door 231.00 that's unreal. While I was waiting a man came in said his car died at the service station next door. Joe asked some questions now he had 12 cars to be repaired !! He left his bussiness to help a man in need got the car to his shop. The man said how much do I owe . Joe said nothing I haven't fixed it yet. Wow if that is not Integrity what is.

Whether it's an engine light, regular maintenance, or replacing parts on older vehicles, they explain everything clearly and never push unnecessary work. What really stands out is their honesty, we've gotten quotes elsewhere and this shop has saved us a significant amount of money while still doing great work. It's rare to find a mechanic this trustworthy, especially in this day and age. We won't go anywhere else.

He answered all my questions without sounding dismissive. So this morning, I came to get the oil change. When you first pull up to the business plaza, you have to drive to the back lot and they are located at "3D" Before I came, Francis kindly sent me a photo of his shop via text so it would be easier to find. The office itself was small, and unassuming, Free Wifi was available which was nice. Met Francis and he was just a stand-up dude. His mechanic took my keys and got the job done in less than 15 mins. Can't really ask for more than that. A+ I will definitely be returning

I found Francis through an online search because of the many positive reviews, and during our first interaction he was friendly, professional, and seemed very knowledgeable. He ordered the part directly from Acura and quoted me a fair price. My car was ready the following day, but when I arrived to pick it up, Francis informed me that my vehicle had been involved in an accident while in his care. He explained that another driver had been speeding through the parking lot and crashed into him. He gave me the other driver's information, and I contacted him immediately. The other driver gave a very different version of events. He stated that he was backing out of a parking space and did not see Francis. He also told me that Francis provided his driver's license information but refused to share insurance information. Now, more than a month later, I still have a damaged vehicle and have not received insurance information from Francis despite multiple phone calls, text messages, and outreach from Mercury Insurance. I trusted this shop to take care of my car, not return it to me in worse condition and leave me responsible for a $500 deductible. What has been most disappointing is the lack of accountability and urgency. Francis acted as though this situation was not a major concern and repeatedly assured me that the other driver would "take care of it," which has not happened. According to the other driver, Francis even asked him to change the story about what happened. I chose this business because of its strong reviews and the image Francis presents, but my experience has been extremely stressful and disappointing. I believe customers deserve honesty, transparency, and responsibility when their vehicle is in someone else's care.
