Quick and honest little smog shop, it's past the car washing area in the back. I was a little confused at first. But they were fast and decently priced. Cheaper than most, considering I wasn't trying to drive 17min for 38$ I paid 58$ for the convenience since it was in my way home and I had other errands to run. Update: the other errands to run were an oil change but connected to this place next door they do oil changes. Synthetic blend was their cheapest they don't do regular, but it was the same price as Lenny dykstras and saved me the trip. Although it didn't come with a free car wash like Lenny's, still very convenient. read more

The smog check at Green Smog Check in Norco was the quickest smog check I've ever had. I was fortunate to show up and not have a long wait. Donnie greeted me and proceeded to take care of my car's smog check. He was friendly, accessible, and got the job done while walking me through the whole process. Not much more to say than that Donnie did a great job, made me feel welcome, and got me on my way home way faster than I expected. Thank you! read more

Super fast and convenient. I was in and out within 15 minutes. Someone was being serviced right before me, so I had to wait about 5 minutes. Once I pulled my car in, the guy didn't take any more than 10 mins to finish the whole service. I initially searched on Yelp, looking for smog check estimates. They were quick to respond and sent over a $53 price quote with a coupon. read more

Green Smog Check - Smog Check Stations Near Me - Norco, California

Very quick service. They were a little hard to find--their very small shop and office are behind the car wash and repair business that occupies most of the building. Drive all the way around and look for the last roll up door on the left side. The guy was there and said to park in the 1 open spot, and we waited less than 10 minutes. Our test took 10 minutes. He has a very small open office where you can wait... it's good enough. Paperwork was quick and easy and he did take credit card/Apple Pay. read more

The green smog check location is easy to get to. The staff is very friendly and they answer any questions. Price is reasonable and they have a coupon. read more

quickly answered my questions in chat before I ever got to the location. Service is extremely quick, and walk-in was available that day. Everything perfect. The only thing I can think of to be helpful is that the shop is located in the farthest bay of a vehicle service building. When I went there was a large RV parked in the lot completely blocking the view of the last bay and I actually couldn't find the service at first. Just get to that last bay and you will be fine. edit. typos fixed read more

Quick and Painless. I have a 2015 and 2017 cars. They were able to inspect and connect without any issues. In and out quick. The only problem is "finding" the facilities. It is behind the car wash. Just drive to the left of the car wash pay lanes and you'll find them at the last stall at the back. ​ read more

My second time here. Place was quick and painless. In less than 20 minutes we weee good to go. Service was quick and cost is reasonable. Just note that it's hidden in the back of the car wash and used EV dealership. read more

Quick and fast and gets the job done with certificate sent to DMV. Fair pricing too. It's a bit hidden behind a car wash so it's easy to miss. The waiting area is also a bit tiny and dingy but it's an auto place so don't expect anything glam. read more
