Having…read moreutilized their services several times in the tiny town of Greenfield I have been consistently pleased with each visit. They are fair with labor and parts costs, willing to research what is needed for rare vehicles and quick to recommend repair priorities to help minimize unnecessary repair costs. Diego manages the daily operations and he is courteous and profession. Reliable at getting back with you when you need quotes or additional information. In the realm of automotive repair businesses where it is common to find businesses with shady practices I am pleased to have stumbled on this gem and will continue to depend on them for my automotive needs.

The guys popped the car up onto the jacks and quickly diagnosed the problem. Unfortunately, no part stores had the "axel half shaft spacer" that we needed. Have no fear! The guys MADE ONE. He cut it from a piece of steel and attached it to the car. It was impressive!!! After three hours they had us back on the road. They could have charged us anything... But they gave us a very fair price. We tipped them extra as we were so happy with their service. I would recommend them to anyone looking for a quick car repair.

My car had some noise coming from one of the wheels and thought it needed an alignment so Leo the…read moreshop owner got it done in less then an hour but it still made same noise. He told me to leave the car for a couple hours so I go back and he had the problem fixed and didn't charge me an arm and a leg!! I was so happy that I had him look at my other cars breaks as the car dealer advised me they would need some pads replaced.. He looked at the breaks and said I was good with those at least for another couple years. I was so happy that he didn't just replace them for no reason just to get a few extra bucks! He only charged me about $20 too! I will definitely be going back to him in the future!!

After sitting for 2.5 hours on Interstate 5 in 112° weather (due to a wildfire before the…read moreGrapevine) my car was not pushing out cool air. I decided to drive out towards the coast and picked up 101and my car started smoking and made a squeaking noise, in other words, my car broke down at Oak Avenue in Greenfield, Ca. I got off the freeway and parked in the Greenfield Fire Station parking lot, where I was assured from the firemen that I was safe. My son in law came from Concord to get me and we drove my car only a couple of blocks to Greenfield Ag Parts and hid my key. I called the next day and spoke to Adam who looked at my car and told me that my water pump went out...he explained what parts needed to be ordered and that since it was the long Labor Day weekend he'd go ahead and order the kit and "try" to get it back to me by Tuesday. A wrong part came so they completed my car on Tuesday, but I wouldn't be able to get back down there (146 miles, 2.5 hours) until later in the week. Today I picked my car up and met Adam. He went over EVERYTHING he did and assured me (and I totally agree) that I broke down in just the right place. I'm thinking that Adam's business works mostly on tractors and farm equipment, but was so kind to drop everything to help this disabled, 65 yr old get back up and running again! THANK YOU ADAM and the guys at Greenfield Ag Parts. You did an AWESOME JOB!!!

I cannot say enough nice things about Juan and Millennium Auto Repair…read more We were traveling thru Greenfield when our car began to overheat. We found Millennium from my phone and limped there, over-heating all the way. Juan diagnosed our problem (it was obvious-even to me) and told us what he needed to do to get us back on the road. Now, all of this is fairly normal, if not expected, from an auto repair place. But...... What impressed me was the trouble he went to to make us feel comfortable while we waited. He had ordered the part to be delivered, and checked up on it to see if it would come earlier then the time quoted (it did) . He had done all the prep work on the car, so when the part came, we were out in 10 minutes. He helped me check options for a rental car (there was none), a u-haul truck (there was none) and when we determined there was no option but to wait, he was very helpful in suggesting a luncheon place that would deliver. He brought our dogs water, and made sure we were comfortable in his waiting area while we waited. This all happened 60 days ago, and I still think about his kindness. And, by the way, the car is working just fine, too. Thank you Juan.
