I have gone to go green smog for the past years and service was definitely the best. However to my dismay, I was told this morning that the somebody else have taken over the business now. The new owner just started three days ago, which makes sense that he seemed to know nothing. They don't accept card at the moment and he would honor the $2 off yelp checkin but he will then tell you that he has no change. He charges $20 for a smog test, which I am ready to pay for but his attitude is simply terrible. I will not return again for sure. Now I'm not even sure if my test were done properly. I'll know for sure when I renew my registration soon. Save yourself the trouble, go someplace else that appreciates your business. Person in charge seemed so sketchy and shady.
