I I needed to get my out of state vehicle vehicle smogged for California DMV plates. Tri City smog was fast efficient and courteous. Highly recommended! In and out in 20 minutes, and they are located very close to the Oceanside DMV. Highly recommended! Mark even help me by loosening the screws on my license plates so when I got to the DMV I could take them off by hand to swap them out for California plates.
