Corona Drive Thru Smog

I live in Ontario Ranch,2nd time coming here ,They've got me in and out,it's in a good location,and it's drive thru.They have shade to sit in and wait,or you could stay in the car,John was great,very informative, great customer service.

This is my go-to smog place. Very fast inexpensive. In many cases you can sit in your car while they do it. Very friendly staff. In and out in 15 minutes.

This is my second visit. Fast service, no waiting in line, in and out in minutes without leaving my car. Courteous service and easy check out. May be a bit more expensive than next door but definitely quicker. Highly Satisfied both times. Thank you!

Super fast, simple. Employees/Owner were super professional and I couldn't have had a better first time smog experience than with these guys. Would definitely come back again and refer them to family and friends

They helped me dial in my smog even though I failed. He helped me find cats that were legal and guided me to make sure I pass next time. Thorough and kind!

Great experience here. Vince was great helped me with how to perform drive cycle and printout after my car failed only cause recent mechanic disconnected battery on minor work done, even though engine was fine. Came back couple days later and passed and very cheap price to retest. Highly recommend. Fast drive thru and great customer service.

I love this place because of how fast and easy it is to get a smog check for your vehicle. The owner and employee are all very respectful and professional. I gave it 4 out of 5 stars because the prices in 2024 for a sedan used to cost $45 with 3 attempts if your vehicle does not pass it on the first try. Now, in June 2025, the price has gone up by $8.

Quick service, standard pricing. Though logically a drive thru, takes the same time as any smog check.

HORRIBLE CUSTOMER SERVICE!! my family and I have been coming here for years,not after today!! It's Saturday around 12:15 pm when I pulled up to get a smog on a rv,the older gentleman takes my paperwork and then turns around and tells me,"next time don't come at lunch time" I'm like ok, then I said we'll how am I supposed to know? You Need to close your shop for lunch if you wish not to be bothered by customers at your lunch hour otherwise customers will keep coming in no matter what time it is until closing time,maybe he was Hangry,but any way this establishment lost a loyal customer.
