Own 3 vehicles and have always gone to the same smog shop in Simi for the past 20 years. I was happy with them, but a neighbor said I should try Jr's Test Only Smog Shop on LA Ave by Ralph's at the 76 gas station. All I can say is WOW... so friendly, accommodating, fast, and so much less expensive than what I was paying all these years. I just always thought a smog was a smog and didn't realize everybody charges differently. And they are a Star Certified station! Check them out on Yelp first; they have such a great rating. It's true... by far the best place to get your car smogged. read more

Went to a few places before coming here. Not naming names, but they all wanted to upsell me on other expensive services when all I wanted was a smog test. Gil performed the test at a very reasonable price. He was fast and friendly. I'm grateful I have a new place to take care of my vehicles. read more

In and out in less than 30mins. Regular price for smog test like any other smog test centers.

Fast, friendly and good quality. Will be back again for future smog checks. 85 character l

Great service - Fair pricing !! I pulled into the shop and within 5 minutes my truck was on the track and being smogged. Thanks again! read more

Currently sitting inside while I wait for the mechanic to change my motor mount after my car passed the smog test. As I normally do when I need service for anything, I trust Yelp when places are recommended and happens to have high ratings. I came in here specifically for a smog. As the test was going on, the mechanic asked me to mosey over because he wanted to show me something. He said the motor mount needed to be replaced. I didn't at all think he was being shady because after he said that, he explained why it had to be replaced. My car has in fact been hesitating when I accelerate which is what he said was the cause. So here I am smog done, now waiting for the part to get here. I told the mechanic that Firestone told me I needed go get my motor replaced and he chuckled. I just knew I was given the wrong info at Firestone. Another mechanic at the shop where I got my brakes fixed also confirmed that the motor was fine. Looks like I just found my new mechanic. This place is conveniently located right next door to 76. Thanks to the two guys working for their honesty. They also honored the smog coupon that's posted on Yelp so I was able to save a little bit. read more

Came here on a weekday at 9am, I was the first person so they got to my car right away. The owner was amazing, worked on my car immediately. I also used a coupon from their website which gave a decent discount (check it out on their website!). I was in and out within 15 mins. Honestly, it was going to be faster but the printer had issues. Highly recommend this place, great price and fast! read more

AMAZING SERVICE! From the first call to meeting in person they are Fast, Friendly and Great Service! Family owned as well! read more

I called JR Smog Center to make sure they were open today (West Valley was closed, with no notice up when I drove over there), and was told they were, no appointment needed. I drove over, Gil was great! The smog on my 2003 Suburban was done in 10 minutes, Gil came over and said " I have good news, you passed", walked me through the paperwork and I was on my way. Great service, quick, and cheerful. I'll definitely be back. read more

These guys were fast, friendly and efficient. Just what you need to get in and out quick. They also have a clean, shaded outdoor seating area for while you wait. I only waited 10 minutes. Glad to recommend these guys. read more

Randomly went to this place as I was getting gas at the 76. I needed to get my scion FRS smogged. The first place I went to yesterday couldn't do it because they said their computer couldn't connect to my ecu and that there might be something wrong with my car. Thank goodness I went here. The owner said my fused for the OBD reader is blown that's why the other place couldn't connect because it didn't have power to power on. He was so nice at explaining all my questions! read more

I own Mercedes Benz ML 350. This is the first time I went for SMOG test. On a Sunday, I was lucky to find this place open. They were fast. Everything done in 15 mins. They also gave me discount.

Great service, honest and professional, highly recommended, don't need appointment and for people busy on weekdays he open Sunday.

They were opened on Sunday, which apparently isn't a given for many smog centers. They also had a coupon which made the price reasonable. They had a nice indoor waiting area and I was there maybe 10 minutes. Super easy and quick! read more

I just got home from my smog check and I'm so happy I chose this place! Start to finish the process took around 8 minutes because no one was waiting when I arrived, but it felt like even faster than that because chatting with the owner and other worker was lovely. I also found them to be more affordable than the other local places. I'll be back with my husbands car very soon. Thanks for the great service guys! Oh and they're STAR CERTIFIED! read more

Hands my best Smog check experience ever. I went online to search for a STAR rated smog check place in Simi because of the DMV requirement that I could only go to a STAR rated station this year. I found JR's Test Only Smog Check and called to see if they were busy. The person on the phone said that they had one person there doing a smog, but should be done in 10 minutes. So I drove over and by the time I got there he was free. I parked in front and gave him my DMV papers. Filled out a quick form with my name and address after giving him a coupon from my phone. In what seemed like less than 15 minutes later, everything was done and paid for for. I drove off and it was simple as that. (The location was convenient too; on the corner of Sycamore and Los Angeles.) The person there was very friendly and nice. When I presented the coupon he had no problem with it. Just a smile on his face and gave me the form where he wrote down the price and had me sign. While talking for a bit I found out that, while his shop is relatively new, he has been doing smog checks for a long time. If you are ever in need of a smog check and looking for a place to go without stress and a good experience, give this place a call. Again, it was the best experience I ever had at a smog check station and will probably be yours as well. read more

What a great and fast experience I had here! Drove up and within ten minutes my car was being smogged. This was so fast and easy I was in and out within 20 minutes including my wait time. Need to get your car smog done than look no further! I do recommend surfing the Internet for coupons though. read more

Super quick and provided excellent service. I'll be coming back here every time I need a smog.

Guy was pretty quick about it. Got my car to pass smog before going to the dmv. Around 60$ or so but they send it off for you also which is nice . read more

Highly recommend this place. Gil is very customer service oriented and respectful of my time. He got me in and out without any unnecessary delays. This location is centrally located and his facility is very clean. I've taken a couple of cars to this new location and I am happy to say I have experienced the same high level of customer service and reasonable pricing. I've known Gil for a few years now and I am very happy he has started his own business. He has many years of experience at a local station. I am happy to support this local business. read more

Came here on a recommendation and it was worth it. The service is fast and very friendly and it is the best price around Simi. Thanks and I will be sure to come back. read more

I have a large diesel truck and when I called Jr, they stayed open a little later to accommodate me. They were so kind and respectful. They let me just scoot over into the passenger seat as the smog check work got done. I work as a contractor and with a lot of subs so as a female in the trade, I judge based on character and service. I was beyond pleased at how well I was treated and how quickly my vehicle was serviced. I recommend this location 100%. This is my new goto location for smoging all 4 of my personal vehicles and my company fleet vehicles. read more

Spoke with Gil about getting a smog test for my motorhome. I gave him all the particulars to see if he was able to test. He then gave me a price. I went later that day and he was able to get right to me. Everything went smooth so a good experience. He does offer discounts so check on them before you go. read more

This place was great! I was so happy to find a Smog Center open after 3 on a Saturday and open Sunday as well! Gil was so pleasant and it was quick and easy. I drove from Agoura and am so glad I did! read more

JR is the man! If i could give him 10 stars i would!!! Came to get a smog was in & out within 10 mins. Very fast, fair & friendly
