Sergio is a great person and a true great mechanic! He is very nice and patient, my car broke down coming back from burning man (I was there early working with my crew) in Vallejo. I called my insurance and had my car towed to Sergio's in San Pablo, and he was really understanding of my situation and allowed my car to get there just as he was closing down. He was nice enough to give me a ride to BART. The next day, he called me and said that my car was literally dead, that it wasn't worth fixing. I will always be greatfull to him as he didn't charge me for the diagnostic, because he is truly honest and told me it took him 2 minutes to know that, as an experienced mechanic. Not all mechanics would have been this honest, I think most of them would have charged me no matter what, not Sergio. I am now car-less, and had to do a few back and fourth to deal with the remnants of my car, and Sergio was really nice and patient about it, although my car wasn't in the way, I felt terrible about leaving it there longer than it should have, and he never made me feel unwelcomed or ever seemed upset. I recommend Sergio to everyone, and I will bring my newest car to him if it ever needs repairs.
