We've been taking our two cars to Sunny for around 4 years. We heard about him through the recommendation of a friend. We find him to be honest, reliable and consistent in the great quality of repairs. I appreciate the explanations of what he's done or what will be needed and feel very comfortable asking questions.
He will tell you if you can wait on a repair rather than taking your money. For example, I was sure I needed new front brakes and made an appointment. When he checked them out, he let me know there was still a reasonable amount of life in them - months. He was willing to change them then but was honest enough to let me know I had more time. I'm taking the car back in the next week or two to finally get the brakes done. And he was right - I got another 5 or so months out of them.
If I ever have an issue with the work, I'd be comfortable raising it with Sunny. Communication is important for any business in my opinion and I wouldn't hesitate to call him with concerns. I just haven't had to!
