I came in today referred by a good friend who gets service done here and I am impressed how amazing they are here. I came in for an oil change. As soon as I walked in I was greeted, which is a plus to be acknowledged. (most places are rude and very pushy) as they promptly did my oil change, they also told me I needed other car maintenance, as well and gave me an estimate. This family owned business is one of kind! in a great area of Diamond Bar and extremely friendly. I am referring my friends and family here!! they're affordable and great in customer service! I will be coming back for the rest of my car maintenance, thank you so much!! (:
