Hi friends! Starting this Monday March 30th we will be closing one hour earlier at 5pm. Everything else will remain the same. Once we defeat this coronavirus and things start to slowly go back to normal we will remain open till 6pm as we always have. During this time appointments are strongly recommended. Stay safe everyone

Business as usual on 02/17/2020. We are OPEN.

Great news! Our new machine and dynamometer are now working. We can smog ALL vehicles that require a CA DMV smog check. Thank you for your patience.

Happy New Year to all Due to the replacement of our Dyno, we will be unable to perform smog tests on vehicles 1999 or OLDER until Monday 15th January, 2018. We can still smog RVs or HEAVY vehicles as they do not require the Dyno. I apologize for any inconvenience caused.

Personal favorite, 1994 Toyota Supra!

Oldie but goody! 1983 Ferrari 308!

Breathtaking Aston Martin!
