I then asked about next week, and that's when the person asked if I visited before. I said no this is my first time, and that's when the person said they only service regular customers. What is the point of the ratings if this Company doesn't allow any new customers? I'm not giving a bad rating since I have not done service here, but if a Company refuses service to new customers, then they should put up a posting/notice for potential new customers. This is more than fair for both parties to be aware of.

My car needed both low beams replaced, an oil change and a tune up. Matt was quick to provide me…read morewith a quote that was reasonable. Scheduling the appointment was easy. Brought my car in, went over some paperwork and was told I'd be contacted once the inspection was complete. Sure enough Matt called me to let me know there were some items found during inspection and which ones needed to be addressed right away. After agreeing to the updated quote they got to work. I came back to the shop prior to being told my car was ready, and I think there may have been a delay in getting parts needed (dropped the car off at 9am, wasn't done until 4pm). Other than that, the quoted price is what I paid, there wasn't any pushing to buy a service that wasn't needed. I will definitely be bringing my car back for the additional work needed.

I requested a quote through Yelp and my request was sent to multiple auto shops. I chose this…read morecompany based on location and called ahead to confirm they could do more than just read basic codes. I had already done my own diagnostics and knew the car was running rich. I had ruled out the upstream O2 sensor, catalytic converter (both new), MAP sensor, and fuel injectors. I explained all of this to Matt before bringing the car in. He assured me they could perform deeper diagnostics with their equipment. After dropping off the car, Matt called and told me they had "confirmed" exactly what I had already told them, and that the next step would be pulling spark plugs--for an additional fee. At that point, I decided to go elsewhere. What I don't understand is why I was still charged the full $85 diagnostic fee, plus a $4 hazardous materials fee and $3 shop supply fee. Plugging a car into a diagnostic scanner does not generate any hazardous waste--no fluids are drained, no chemicals are used, and no parts are replaced. There's nothing about a basic scan that would justify a hazardous materials charge. That kind of fee typically applies when disposing of things like oil, coolant, or other regulated waste, none of which occurred here. In the end, I paid $92, wasted time and gas, and learned nothing new. The most concerning part was Matt admitting he didn't even know spark plugs would need to be checked as part of further diagnosis.

While waiting for AAA to change out the tire with the spare, I scrambled to reschedule my doctor's appointment in Brea, while canceling my meeting in Chino Hills and dinner plans with my daughter in Monterey Park. I was supposed to be everywhere that day but ended up stuck going nowhere. I went on Yelp to find the closest tire shop that had the cheapest tire available same day because I wasn't feeling comfortable going back on the freeway on a spare. I was able to secure a tire for about $145 (tire, fees, and tax) on Tire Choice's website and also made an online appointment to get it replaced within the hour. I was mentally exhausted and just really wanted to head home and worry about searching for deals on better sets of tires later. When I got to Tire Choice, I was quickly greeted by Gina at the front. I told her exactly what I wanted to get done to avoid wasting her time hoping to up sell me better tires, and she got the message that I really just wanted to be able to quickly get back on the road again without pressuring me into changing all four of my tires. Gina was a doll and very pleasant to converse with. She was able to effectively multitask (answering phones, getting quotes for other customers, giving instructions to the mechanics), while we shared stories about our kids (my children and her fur babies). I think I spent 20 minutes max there and my tire was done. I was so happy! My overall experience at Tire Choice Auto Service Center in Diamond Bar was amazing.

This is my own personal experience so don't let my review falter you from reaching out. I reached…read moreout for a dented rim repair as shown in my photos. The repair came out great and it took around two days. Tony came to my house and picked up the wheel. Unfortunately the paint correction did not match the rim and also my tire was leaking where the repair was made (it wasn't leaking even when the rim was dented). So I contacted Tony again to see what he can do. He said the paint came off the machine and that's what it analyzed it as and was willing to do it again so I said sure since the paint came out black instead of blue. He also offered to check on the tire and rebead the seal. So he picked up the wheel again, and this time it took almost two weeks to be done with the repair and this was only the tire portion. He advised that the paint correction would take another couple of days. Honestly just wanted the wheel back since I was out of a car for two weeks already and who knows how much longer it would take to get the wheel back. He came and dropped it off and installed the wheel and the tire is holding air for now, but he did recommend me to just get a new tire if it leaks again which I will do. This time though, when I got the wheel back, it had a new chip near the center which wasn't there before from the original pick up nor the first repair. As far as value and convenience of picking up and delivering goes, I'd say it's fair and beats the competitors. Otherwise, I wasn't too thrilled about the repair. Update: Bumped up one star since tire repairs aren't part of their job description and Tony went out of his way to do it. Leaving it 3 stars due to paint issues and poor communication where I have to ask for updates every couple of days.

He again scoffed and said it doesn't work that way and told me to just go back to Longo. I was really hoping to give a small business a shot but seems like he doesn't care to gain more business.
