OMG, I LOVE this man & his place….especially since I HATE taking cars in for service & repairs cuz I get taken advantage of, however subtly, ALL the time (usually b/c I’m a woman) & always leave paying for stuff I realize later I really didn’t need or could postpone later, especially in this bad economy. I drove 40 min to get (it’s actually north of Sonoma Square) & I would come back over & over, & have my cars towed here for deciphering, in a heartbeat!!
“Love the Timeliness”
We had a great experience at William’s Auto… We called first thing in the morning and they were able to get us in that day. They were friendly and exceptionally helpful.
It is so refreshing to excellent customer service. Camille was so helpful, knowledgeable and friendly. I brought my car in having transmission issue’s, they quoted me a price and that’s exactly what I paid. My car was ready on time and everyone was professional! I’ll definitely go back again!!
