I recommend this place. Bill helped us and he was amazing. He was fast and helpful and just a great guy. The entrance is off of Grove, not Arrow. Just pull up in front of the roll-up door if there's space; otherwise, park in the small parking lot on the south side of the building. read more

Bill was great! Was able to get me in right away and honored the coupon price without any haggling. Will definitely use him again in the future. Highly recommend read more

Owner was very Friendly and he was done in no time. I recommend this place to anyone who is looking for a quick stop

I called to ask about their smog check coupon pricing and was surprised to learn that SUVs cost an additional $10 which is fine but the person I spoke with on the phone was very rude. A friendlier attitude toward potential customers would go a long way. read more

Sam's Smog - Location of place with Jayden working in my car - Smog Check Stations Near Me - Rancho Cucamonga, California

I was thrilled to find a smog check location with competitive pricing near me. Saw online that many places are charging almost $60 for a smog check. Brought my 2015 sedan in around late afternoon. No appointment necessary. Staff were very friendly. They had a seating area for customers inside the shop which was a relief on this hot day. I presented the coupon I had for a $36.75 (plus $8.25 cert) smog check. I was there for no more than 10 minutes, paid, was handed my PASS certificate, and I was on my way. Will definitely be recommending this business to friends and family. Be sure to check their website for the most up to date coupon. They accept all major credit cards but do attach a 3% transaction fee. So bring cash if you want to avoid the fee. Thank you so much! read more

Just called Sam's smog and asked if I needed an appointment. They said come on down we close at 3 (this was at 2). I got there and was greeted by a nice man and told just to bring it up. He took my smog paper work from DMV and started right away. I know I may have just got luck on the time and only a couple other people here but honestly how nice the gentleman working was (I think his name was bill) really made it a great and easy experience. read more

Smog check, good prices, friendly, fast service. Definitely be returning when needed.

Great customer service, friendly and well priced. Definitely will use him again. He got pretty busy while I was there

Excellent service!! If I could give him 10 stars, I would. He checked under my Truck to be sure there were no leaking hoses or other issues. He provides excellent customer service, and is a very nice person. He is very friendly, and I felt like I'd known him forever. I will be coming back to Sam's Smog the next time I need to smog my truck. Thank you again!!!! read more

I knew beforehand, I had a chose whether I would mention the coupon because that it is the first picture you see when you search this place on yelp but I've given him the benefit of the doubt to mention a coupon but I ended paying full price. Honestly and generosity is dying into non-existent these days but not sure why I hesitated. I live less than a minute from here. Be warned, mention the coupon, it's worth the discount. read more

Thanks for the fast service and upfront pricing! Was in and out in a flash. Also, friendly and professional.

Bill provided a welcoming and efficient smog service. He honored the promotion with no issues. Tip: pay cash as there is an up charge for using card. read more

I took my car into this shop to run the smog test and I got done dirty. The middle eastern man that ran the smog couldn't explain to me what was wrong with the car. He stated I got a "fake" cat because numbers weren't matching; however, the sticker needed to verify the numbers on my car was not even on the car. I drive a 2003 Honda accord and the cat number came back to a Honda element of the same year. After I did some research, I found out the Honda element and Honda accord parts are interchangeable. These cars have the same engine. He marked my car as tampered in the system, which is really bad. After additional research, I found out he could have done a test smog prior to actually running it. I feel as if I was taken advantage of because he was quick to offer mechanical services at a very expensive cost. I DEFINITELY WOULD NEVER GO BACK OR RECOMMEND. read more

Gil is great! Super quick service! Took 5 minutes...Totally recommend this shop.. will be back next year!

Went to get a smog check at this place, my car didn't passed because I had just changed the battery. The owner recommended me to drive the car for about an hour on the freeway and then come. He rechecked it (it passed) and he didn't charge me a re inspection fee. The owner is pretty chill and straight to the point. read more

Great guy! Respects the coupon and did our smog check very quickly. He was responsive and friendly. Good value and we were in and out.

The owner was being helpful and fast. For 40 dollars and great customer service definitely will come back ! read more

The new owner, Bill, is so helpful and kind. My car didn't pass smog the first time so he let me know what needed to be fixed and said I can come back and get it resmoged once I fixed the issue. I came back over a month later and he retested it for me, TWICE. Thank you so much Bill! read more

Glad to find a smog check close by. Very helpful and fast. Coupon on their website is still valid (around $40 including certificate), but $10 more for SUV. Price was very similar to others, but was a very convenient location for me instead of having to drive farther. read more

Basil very honest and it was exceptional service. And after my car failed the smog check i brought it back a couple days later and it passed. The retest was free too. Basil was very friendly and I would highly recommend him to all my friends for a smog check. read more
