I was quoted high and low for the job from many other shops but I chose this shop because it stood out in the best ways. I meet the owner as I was searching shops for quotes and stopped by early (9am roughly) met the owner, he had me feeling comfortable for he is a friendly guy. I told him how I have a 2018 Chevy Silverado with a messed up transmission he told me that he's very familiar with the brand and the showed that he's definitely knowledgeable and confident which other shops happen to lack. He on the spot quoted me for the best possible opinion with my truck's condition I liked that he mentioned a 3 year warranty on parts and labor for the job. He insured me that the truck would come in and would be done a week from the day I leave my truck. The price was absolutely reasonable for the hefty work load (5k). I had went to other shops they said they could try and address the issue directly and I could spend less but those people lack confidence in the work they happen to mention that they have only done one other Chevy prior and that it was difficult they lost me at that point. I have spoken to the dealership and they nearly quoted me for double the price with no close date or availability. This shops was the best bang for my buck the reviews brought me and and they absolutely delivered. I have been driving my truck daily since for a little over a week now and not a hiccup or tick or leak in sight they really did there thing. They was punctual on the timing and they know what there doing which is key in a highly sensitive job like this, price was good, owners a cool guy as well, the warranty is amazing. I can't figure out what more you would want from a shop. I'll be back for more work I trust them with my vehicle which personal friends know that's not common for me to trust a shop with my cars or truck

When I first brought my car, he did a full scope of the car to familiarize himself with it. They are extremely organized, as they keep all the notes computerized for future purposes, and give the option to call/text/email for service notifications. In the last couple of months, I've been to Ultima for a couple of repairs plus an oil change, and it's been a fantastic experience. Yuval explains everything thoroughly, and all repairs have been fixed to perfection. It's really a breath of fresh air to have an honest mechanic who cares, communicates sincerely, and is extremely experienced & skillful... and their price is fair. Definitely plan to go to Ultima for future auto services.

That didn't make sense since the check engine light came on very sporadically. Turns out there were a few things wrong and it wasn't the engine.
