I have used Inland Smog for many years and I have found them to be one of the best auto repair facilities in Corona. Craig and his staff are not only experts at getting you a smog test when needed, but they are experts at diagnosing mechanical problems on most any type of vehicles. I have taken both my modern hybrid cars and classics to Craig with excellent results each time. I highly recommend Inland Smog to anyone looking for an honest auto mechanic.
