What Our Customers Are Saying

Great service the gentleman is very king and professional provides great service and your in and out quickly, I recommend this place.

Inspections and Emissions, near Pasadena, CA

, 09/05/2025

My 2015 Nissan Rogue was due for its Smog Check. My check engine light was on when I brought it in. I had the light checked at auto supply store and they said that the oxygen sensor was bad. Arthur looked at the printout paperwork and said that that may not be the problem. He popped the hood and he found the problem within less than a minute. One of the hoses was not connected to the engine. After another diagnostic check found that there may another issue but suggest that I drive a few miles to reset the emissions computer. After I drove the recommended miles I had the car smog check and it passed. I've brought in a number of cars we've had to Arthur. He is very honest, friendly and knowledgeable. I highly recommend anyone to bring their vehicle to this establishment. Definitely 5 stars.
