He lives up to his name but service is great. Straight to the point, no nonsense. In and out in short time.

We have been going to Grumpy's for years. I love no appointment is needed so I can easily fit it in to my schedule. Quick smog service and reasonably priced! Highly recommend. read more

The guy who performs the smog checks is thorough and efficient so much so I went back for a car repair. He was able to explain the issue in simple terms and as a female car owner I felt comfortable asking questions. He was very patient in answering. For smog checks it's a first come first serve basis, but on both occasions there were only one or two cars ahead of me and the wait wasn't that long. read more

I've been using Grumpy's for 4 different cars for years. Always interesting to chat with, does the job processionally, and has reasonable prices! read more

Excellent service and always shows great courtesy to my wife and I when we have brought our cars for smog checks over the years. read more

The place was easy to find and not on a particularly busy street. He was in fact a grumpy old man but I was in and out in less than 15 minutes. There's no "good morning" or "thank you" but what can you expect for a place called Grumpy's? I told him I found him on yelp and he gave me a discount. He made some conversation with me. It's a no frills place and no waiting room. Just a couple of dirty chairs and a parrot. You may have to back your car all the way to the street from the garage FYI. read more

Grumpy.. yes Fast service.. yes Quality work.. yes Definitely give him a ring if you need a smog check. Called him up and was surprised the name matched the energy. But he's straight up and will get the work done. It like these other shops that dance around the price and service to expect. read more

I get the personality thing, but no one goes to get their car smogged and to be berated at before 9am for entertainment. This isn't Karen's Diner. You'd think there would be a level of professionalism, but there isn't. Boomer at its finest. read more

Grumpy is a great guy, I arrived with out an appointment and he fitted me in straight away would recommend for smog tests in the Chatsworth area. read more

I was in the neighborhood and needed my truck smogged.. looked at a few places and decided to call and see if they were available. Surely enough a grumpy elder man greeted me and told me his name was Grumpy.. I said ok el senior Grumpy.. and everything was amazing.. prices are great.. read more

Grumpy's Smog Center - Front view - Smog Check Stations Near Me - Chatsworth, California

He may be a grumpy old guy but efficient in his job and fast. He doesn't waste your time and that's why I like the grumpy guy.

Came here for smog check- Javier , super nice and friendly fast service. Highly recommend.:) go there to check out the cool parrot:)

This man is a miracle worker! He was able to repair the issue in my '99 Camry that caused my check engine light to turn on. Without Grumpy's expertise, my car wouldn't have passed a smog check. To top off the excellent service, Grumpy charged me a very reasonable and affordable price. I am very grateful to him as my car holds sentimental value to me and pray for God to protect and bless this man. read more

Fast easy got the job done. Quality service Value reasonable for smog testing I highly recommend

Hands down the Best and Reliable smog center in town. No waisted time, he's efficient and old school. Driving miles to get to him has been worth it all these years. Never disappointed. Worth every penny. Value at its best. read more

Phewww the name is right. Called to get a quote for smog and he said "really you need a quote?" Uhh, yeah man it's worth it to call around and save. And I'd pay $20 extra not to deal with this guy. Wow. read more

I'll probably not be back because the shop is decorated with political Flags and I don't like mixing politics and business. It was quick, first come first serve. Didn't have to wait. Took 5 minutes from pull in to pull out. A bit more than others in the area, but I didn't have to wait. . read more

Been there a few times. Very good experience and service. Grumpy is a great guy. Very accommodating. Will be there again. He's our go to SMOG guy. The Heslin's. read more

Grumpy's Smog Center - Smog Check Stations Near Me - Chatsworth, California

I needed to sell a car on Monday and the buyer requested a smog check on Sunday. Only shop in town opened for Sunday smog check was Grumpy's. Very nice and pleasant technician, not at all Grumpy hahaha. All these snowflakes are way too sensitive these days. He's just a genuine old school dude working hard to make a living. If you can't handle this dude's personality, you're the problem to today's society, not him. read more

Nice guy. All went smooth. Fair price. His assistant or other guy Jeff very knowledgeable too. read more

He accused me of having my receipt and the yellow copy and I did not. He said he gave it to me and he did not. I signed the receipt for my credit card and I filled out and signed the form he gave me on the clipboard. After emptying out my purse and my pockets to show him I didn't have it , all of a sudden my receipt and the yellow copy appeared in his hand and he gave it to me. He sure lives up to the name of the business. I will not be returning to this place. There are plenty of smog centers around. read more

Please doing business here at Grumpy's. Got my Corvette z06 smog checked with no issues.

So Grumpy lives up to his name. I don't care about his bedside manner. His price for a smog is reasonable and he does it right. I did emmision inspections for 20 years and left the industry so paying for something like this really sucks for me. Call him up and show up on time, he'll make the process as smooth as possible. read more

Very fast, convenient, waited for service. Technician was friendly and efficient. Would highly recommend and use again!

He's done my RV and cars for years. Looking forward to going there again this week. Very professional.

I found him six years ago, and is great. Does a good job, thorough, didn't have to wait, and his price is very reasonable. Besides coming to him for my smog check, he's personable and I always like to hear what he has to say. He's old school, and reminds me of my father's generation. I hope he's around for a long time more!! Thank's Grumpy, you are appreciate! read more

There are a LOT of smog places around. Grumpy gets the job done, but I've had it with his attitude. Yesterday I bring a car I just bought at auction and his first sentence is "oh, you brought me THAT?" followed by a lecture about how the seller should have smogged the car, etc. Then he tells me to come back the next day, even though he was open and had no cars in front of me. I am taking my business elsewhere, as it doesn't seem like he wants it much. read more

Been going to him for 15 years. Hes fast & very good. Theres no waiting room area, so he asks that you just sit in your car and he'll take you next. read more

The name is perfect for this place. I called to ask how much for a smog check and when l told him the year of the car, before I could even finish the make and model he hung up on me. Giving them the benefit of the doubt, I called back 4 more times and got clicked on each time. If they don't want to do a specific year car just say so. Would it not be so much more professional to say I really don't do that year car? Absolute unprofessionalism, I live in the neighborhood and my whole family USED to go there but no more. I will be sure to let all my neighbors know as well. read more

I called around to a few different star certified smog places that refused to smog my 1994 Chevy blazer. My truck is nothing special, but most of these places did not want to take the time to smog cars older than 2000. Grumpy did not have any issues taking the time to get my car smogged and sent me on my way once it passed. I will definitely be back with my other cars in the future. read more

Grumpy was very helpful, with a fair price and very efficient. I had a good experience with Grumpy! And that's why he has 5* across the board. read more

If you have an older car that needs a rear wheel roller tester (or not) Grumpy is your man. He's been at this location for years and his knowledge is award winning! He gave me advice on another issue I had with my car that was totally unrelated to the smog cert. He knows his stuff. And yes, his name is Grumpy... read more

Grumpy was extremely grumpy, as advertised. A little rude and offputting, but also did exactly what I needed him to do which was smog check my car without an appointment. Asked me why I ended up there and I said he's close to my house. I ended up there because I didn't go the other 385 feet to the Chatsworth Smog Center which is where I was headed. He didn't have a mask on which would bother me but I am vaccinated so unlikely to die from COVID. Can't say the same for him. read more
