Whenever I need a smog, this is the place to go. I have been going there for many years. No appointment needed, no delusional offers, no drama. Affordable. Jared was the person who helped me last time. Extremely friendly, kind and fast service. read more

Jared was super helpful and quick. Good experience. No waiting, fast service without an appointment.

This place rocks!!! They will do all that it takes to make you a happy camper ... I will never go anywhere else for my auto repairs and I live in Nevada !! TRUTH The end !! read more

Super nice and very fast. Highlight on nice though. Already recommended to a few folks.

Quick service and great process!!!! Everyone was extremely professional, polite, and nice! read more

Rays is the only place to go for all of your automotive needs! Truly the best swift service. Best bang for the buck without sacrificing anything. It's rays or nothing in our household, thank you! read more

I've been living in grass valley for almost 10 years and rays has always been the best place for smog. They are so polite and fast. Even once years ago when I failed they were so helpful about what to do. they have always been the best price, service and I'm never there for more than 20 mins. Good, fast or cheap you get all three here! Never go out of business Please!! read more

I took my truck here knowing it needed work to pass and that they do repairs. They told me it needed an EGR hose and that they couldn't get it so I should buy it online. I did and when I got the part called to ask when i can bring it in. The owner was very rude, told me I probably didn't have the right part (I definitely do) and to take it to another shop to get the small part installed. A huge inconvenience to take my car to multiple shops when this place claims to do repairs and advised me they could do the work. When I I tried to ask why he would turn me away after telling me to go get the part and bring it in the man on the phone hung up on me, and when I call back hung up two more times. I have 4 vehicles and am happy to pay for repairs as needed so another shop would be happy to have the business. read more

Great experience for my smog check. I had just sat down to do paperwork and my car was already done! I was out of there in 15 minutes. Very professional, knowledgeable and friendly staff. I will definitely only be going there for service in the future. Also a great price. Thanks for your help Jared (who is definitely not a hippie!) read more

As quick as IN-N-OUT Burger. No problems with the work nor the staff. I was amazed how little time it took to get a smog check on my 2007 Toyota Corolla CE. read more

I have been using Ray's for years for smog. Over the last couple of years Ray's has been my go to for all my auto repairs. Josh the owner has great intregity and will always give me an honest diagnosis. I recently purchased a used car from him because I knew I could trust he would not sell me anything not tested and inspected. He cares about his reputation as a resident in the community and follows in the footsteps of his father who obviously taught him ethics, caring, honesty, and fairness. I might add I have had some wonderful conversations with Josh and he always spend what time is needed to explain any repairs and recommendations. I am a proud supporter of Ray's Radiator! read more

Zero customer service treated me like trash talk to me like I was an idiot such sarcasm in his voice. This used to be my go-to for smog. I will never give them another dime read more

Had a long wait at another smog test place. Left frustrated. Someone recommended Rays. Fast and very friendly! Very affordable also!

Great place great people they have working. Very friendly and very quick. We always go there for all our vehicles.

I have been coming here for almost 6 years maybe more. Quick, honest and they get it done. They are too busy for your feelings which is fine with me. I watched an elderly man pul in and look like his medication was off, was asked several times to put his vehicle in park, started rolling towards me which made me jump, rolls backwards still not putting it in park and then roll forward over the manager's foot. Unphased. Kept going and didn't make a big deal about it. Probably knew something was off. That is a freakin warrior. So if you need to have your hand held, there are other places you can pay more for that. read more

Quick and to the point. No appointment and I was out of there in 10 minutes. 1999 Jeep so it had to be put on the Dyno. Don't expect friendly chit chat, they just do the job. Price was exactly as quoted upfront. read more

The mechanic helping me was Rude and too fast. I actually felt like this man was maybe even discriminating against me asking me to take it somewhere else. read more

We went and got a SMOG check done a while ago now and brought our car in it failed the first check but when we did the retest and it passed the guy who helped us was extremely rude. We took the car elsewhere and he acted as if that was a personal transgression against him. Extremely unprofessional towards us after the fact. Also every response the owner has given out to these reviews is extremely unprofessional and rude. Arguing with customers experiences and trying to prove them wrong doesn't make me want to ever go back. I thought time was supposed to give you experience and patience not however we were treated here. The only advantage to this place is how fast they are which is why I'm leaving this review with 2 stars instead of 1. read more

My father who is a disabled Army Veteran and is a local hero (stopped a mass shooting from occurring at the hospital in 2006) went in today to get his smog recheck completed one day late. Instead of politely explaining their policies they were rude to him. My dad then spoke with whoever was in charge about the bad customer service. Rather than addressing the issue they refused service to my dad after he drove 40 miles in a 35' RV to get the smog completed. I can't believe they would treat him like this. DO NOT GIVE THEM YOUR BUSINESS. read more

If you want an honest car repair shop, go to Ray's Radiator. Josh, Sim and the rest of the crew will bend over backwards for you. These guys are the best and most honest mechanics I've ever dealt with. I can't say enough good things about them! read more

They have just a terrible attitude there. I would avoid at all costs. They are not about the customer experience. Plenty of other options in Grass Valley. Do yourself a favor and explore them versus this place. The owner Sim is very abusive and argumentative loves to pick fights so the other reviews here are totally on point. read more

Rude, and condescending kid working there. Asked a question about results, and his reply would've gotten a serious attitude adjustment given to me when I was his age. Do better! read more

I needed a smog check and hadn't had time due work conflict. However, I happen to have Friday off and thought let's get it down!! I drove up to see if they could take me - this was around 8:30am. Here's what you should know. No appointments needed, they do it 10 mins or less. They are thorough and polite. It on the corner and they are busy- i would definitely recommend them. I'll see you guys again in 2 years. read more

We got great honest service here. Came in for a smog check & used car once over. They found issues with the car and didn't expect us to fix it with them, just honest and transparent. We left our car with them and they fixed it without inflated pricing that got I at other shops. Small family owned honest work. Will go back! read more

It takes a lot for me to have a bad experience somewhere, however, this was a terrible one. I'm not one to write bad reviews on any business, because I am a small local business owner myself, but this one earned it. While a family member was having their vehicle smogged I pulled in to drop something off with them. This would have taken 30 seconds or less. As I exit my vehicle I am asked "can I help you?" quite aggressively. When I mentioned that I would be very quick and I was just dropping something off to someone (one of their paying customers), they very rudely told me I could not park in the parking lot and I must move my vehicle immediately. Mind you, there is no cars in the parking lot and mine is completely out of the way of anything going on in their parking lot. When I said "I'm literally dropping something off, it'll be very quick" he demanded again that I park somewhere else and that he didn't care. I'm not sure how a business can get away with being this unprofessional to friendly community members, but I know I won't be taking my business there. In the end, I wouldn't care if I was asked to move my vehicle across the street, but how difficult is it to just ask me politely instead of demand it rude and aggressively? read more

What a ripoff. Don't recommend these guys. Took my car in for a smog that they failed for some BS and told me I'd need to leave my car overnight for an estimate on repairs. After giving them $40 to get my keys back I literally drove to next nearest smog shop and my car passed perfectly. Go here at your own risk! I won't be back... read more

Rays is a joke they are lazy and dishonest! !! When I first got there he proceeded to tell me how much he loved my truck then he failed it because there was something not hooked up right I asked if I could hook it up and he said no it would have taken me 3 seconds so he failed me and after he failed me he proceeded to negotiate on buying sounds to me like he was trying to scam me take it to Karls repair he's honest and he doesn't mind tinkering with things JDS P.S truck passed no issues read more

My usual smog check place lost their tech, so they sent me here. Nothing fancy, but they don't mess around. I was in and out of there in about 10 minutes. Nothing pretty or comfy-cozy, but fast, efficient and easy. The price was right and I got what I needed. read more

This shop is filthy and extremely unaccommodating. Seems like I'm not alone in having a bad experience there. The owner seemed professional, the worker comes across rude and pushy. read more

The owner swore at me multiple times and told me "get the fuck out of here," because I didn't understand what he was telling me to do. He said I didn't want to understand, Then called the police and I called as well. But I had signed the paper they give you when you first get there. So I was contractually obligated to pay for the failed smog. It was literally getting down there and wiping off the catalytic converters to read the number, which I did when I left with a paper napkin and a little water. He said they tried to wipe it but I tried and did it in about 30 seconds. This place is a scam unless everything is just a walk in the park for them. They don't want to help the consumer get a problem fixed they just want to scam people whenever they can. The epitome of small town bs. Please don't go there, don't support people like this. I've never written a review on anything but after this happens at 9 in the morning on a Tuesday. It was pretty triggering. I'm a very passive person unless you want to treat me with disrespect. The owner is a joke. I even tried to bite my tongue and say my bad for not understanding but I'm just trying to get this done. He wouldn't acknowledge me trying to defuse the situation and kept repeating 40 bucks. Cussed at me more and I drove off. He even tried to grab the keys from my truck but I got them first. Haa what a joke read more

Every time I come here, the staff are efficient and respectful. Also very no-nonsense. No complaints about this place at all!

I went here for a walk-in (they don't do appointments) smog check and left within an hour. They were very quick and efficient considering how many people were there. I am most happy because Ray's Radiator was the only business in they area that was able to perform this service today. read more

Got a smog check done at Ray's last week. The staff was friendly, helpful and extremely quick. I was in and out of there is less than 10 mins. Nothing but good things to say about my experience with them. read more

I've been going here for years for smog checks. Always super fast and friendly. I don't think I've ever spent more than 10 minutes getting in and out for a smog check. read more

Dishonest, ill-mannered, rude and a filthy shop. Do yourself a big favor and stay as far as possible from this place. I didn't know any better and took my car to Ray's for a smog test. They tried to perform the smog test but said they couldn't perform the test because the check engine light was on. It wasn't on when I drove in. I couldn't figure out what happened until "Ray" or whatever the surly dude's name is, said he could track down the problem for $90/hour. When I ran the OBDII scan at home it gave an error for the fuel injectors and I found a disconnected wire. I have no proof that "Ray" disconnected it but the check engine light wasnt on when I took it in. If you look at the other reviews it appears as though these low-lives try a shake down everyone that comes thru there door. It may be the most disgusting business I ever visited in my life. read more

We tried to give these guys our business, mostly because of Josh (who is personal) and the fact that they are close to us. We will NOT use them again! The owner Sim, or Ray? or whatever his name is an a**ho** as well as dishonest! They will not fix your vehicle..in fact, will charge you excessively for something other than what you brought it in for...The mechanics led by Sim are unable to diagnose the problem correctly... Bad business .. Sim could care less about customer service .. We are taking our business elsewhere !! Steer clear of Ray's Automotive..there are other shops around that know what they're doing and will treat you much better . Sim just doesn't give a s**t ...FACT ! read more

This is the worst place to come. The owner is rude and is dishonest! I brought them my 1990 Toyota pickup it passed 2 years ago no problem. In fact I paid them to fix it 2 years ago. Now they failed it for modified fuel injection and pointed to the disconnected a/c parts and said it would be $90 to fix. I unhooked it myself and brought it back and they said it would just fail again unless I paid them to fix it. I will never Be back! read more

Went to Ray's for a smog certification on my 1998 Toyota. Their service was fast, friendly and reasonably priced. Can't beat 'em. They are my first choice from now on. read more

Only STAR certified smog check near me. They took in my car as soon as I arrived and I was done in probably about 10 minutes. The mechanic also pointed out two hoses that were deteriorating so I could replace them myself. Really appreciate the honesty. I will be going there next time. read more

Total scammers, avoid this place at all costs. I've never seen anything like them before, and I'm 34. They overcharge to inspect your car when a check engine light is on big time. Check it out, call other shops, Ray's is ridiculous with absolutely no justification except for that they are the first auto shop when you get off the highway in McKnight. They're also one of those shops that looks for problems, they don't look for ways to get you back on the road at a reasonable price. I ended up getting work done on my car somewhere else. I also got a smog check at Rays, my car passed the state digital inspection, but didn't pass their "visual" inspection. Which, from an observers standpoint, looked like a miner was digging for gold under my hood. I said okay, didn't get any work done at this shop again, and took it to another shop down the road for a smog test. Then something crazy happened - my car passed smog instantly at the second shop!! I wonder why? These guys are scammers, plain and simple. Go spend your money somewhere that the shop is honest, and cares about you and getting your car back on the road. read more
