"Johnny said he noticed I had Military tags and gave me a Military discount! Forgot to mention that I called other places in San Diego, Discount made it cheaper! Can't say enough good things about this place!"

"Mike was very informative and had me in and out within 20 minutes. I had an older 1996 car so it had to be tested through the tail pipe, which probably doubled the testing time. Will return and recommend all my friends and family here."

"Johnny explained to me the smog check process and didn't make me feel dumb when I asked a bunch of questions. I was in and out within 15-20 minutes. His prices are also very reasonable as well."

Our Services

We can perform smog check on all vehicles.

We're equipped with the latest in innovative technology, which meets the demand of the smog check program.

Some vehicles required a smog check at a Star Station. A directed vehicle is required by the state to have its smog check performed at a station meeting certain performance standards. Stations meeting these standards are certified by the Bureau of Automotive Repair (BAR).
In California, vehicles must undergo a biennial smog inspection (every other year) in order to renew your registration. Gasoline vehicles 6 or less model-years old are not required to have a biennial inspection. However, these vehicles must have a Smog Check performed if the vehicle is sold or being registered in California for the first time. Vehicles six or less model years old will pay an annual smog abatement fee for the first six registration years instead of being required to provide a biennial smog certification. The registration renewal notice mailed to you by the department will indicate if a smog certification is required.
New residents to California will be required to have an initial smog inspection when registering your vehicle. Both diesel and gasoline powered out-of-state vehicles require a smog check for initial California registration.
Smog Inspections are also required anytime a vehicle is sold or bought in California. During a title transfer the Department of Motor Vehicles will not allow a vehicle to be registered unless it is presented with a valid smog certificate.
Since 2010 California has required all diesel trucks and diesel passenger cars which are 1998 model year or newer, and weight 14,000 GVWR or less, undergo a biennial smog inspection similar to their gasoline counterparts. Diesel smog inspections are required during a diesel vehicle's initial registration in California and once, every two years, thereafter.
A hybrid electric vehicle is defined as any passenger vehicle that uses an electric motor as a part of its propulsion system, as well as an internal combustion engine. As of April 15th 2015 Hybrid-Electric vehicles are required to undergo a smog inspection biennially when the registration renewal is due, during initial registration, and anytime a change-of-ownership occurs.
