I've been taking cars here, and recommending this place for years. As of lately he told me I needed a catalytic convertor, I got it, about 400$, But found out there was nothing at all wrong with the old one. I figured OK you can make a mistake, I don't claim to be perfect. So I tell him about it two years later when the smog is due again, and he blows up, has a tantrum like two year old. I've witnessed him yelling at customers before, I had no idea. Danny is not someone I will do business with again.
