I've been using Yotaluma for YEARS and can't say enough good things about Ryan. We recently moved from the area (a two hour drive) and I STILL bring my Toyota Matrix back to Yotaluma. Honest, fast, responsive. Yes, as good as it gets. Larry F. El Dorado Hills, CA

I had a long time mechanic who passed away. I was referred to Williams Auto Care and will be a long time customer. They are fantastic. Fair in pricing, detailed in their work and customer oriented!. They identified future work, but did not proceed with the work!! I appreciate that. They will get all my business.

Tim is the Most Amazing Mechanic I’ve seen in my 40 Years in the Car Business ! With 3 ways to fix the blend door ! He choose the one for the customer’s best pricing ! The dealer low balled Me & He took a 8 hour job to four hours . The factory set the HVAC actuators to the wrong pressure ! Tim re-set the actuators In The Body Control Module (BCM) after he was done . We now have heater & A/C back again .Tim is a Get Her Done kinda GREAT mechanic! Thank you so much ! After 40 years in the car/truck business He is the go to Guy of Auto Repair . ??????
