5 stars ! I called and got an appointment same day to complete my smog check. Sean was very nice and helpful. He offered water and a cozy spot to sit and wait with my dog. I even got new rhinestone valves. I recommend and will come back !
Called for a smog, was scheduled same day. Sean was very professional and friendly. The shop is clean, had seating available. The smog was quick and also checked my tires. I have already recommended this place to my family and friends.
Came in without a reservation for a smog check and serviced very quickly. In and out in no time. Sean, the owners father helped us out, he was very friendly and filled up our tires and topped off our windshield wiper fluid for no extra cost. Extremely friendly and cozy environment well decorated.
I was referred to Darling Smog & am very pleased with the service! Nikki & her dad were so great and I was in/out in no time! I highly recommend for your local go-to Smog service! A++Did you know that rats can climb up into your engine & leave their food scraps? We'll, I didn't until they found snail shells in my motor! Lol - Gave me great tips to keep the rats at bay! You want to know? Guess you need to visit Darling Smog!
Great place to get a smog check! Quick, friendly and reasonable price! I’d definitely recommend!
Friendly shop, Nikki was very helpful and informative. Very quick service, highly recommend!
Great smog check shop! Loved the Corvette on the lift, comfy waiting area, and friendly service. They gave helpful advice on my brakes and a sound I mentioned. Fast and efficient—highly recommend!
Called the shop to see availability for the day, they were able to get my smog done in 20 minutes. Offered me water and had seating available. Super easy and super fast. Love it, will definitely be coming back for future smog checks.
Had a great experience taking my car to Darling Smog this morning. Nikki and her team were welcoming and professional. There was a comfortable place to wait and the whole process took less than 20 minutes. Would highly recommend!
I have been taking my wife’s car here for a smog test for the past 4 years. I was pleasantly surprised to see it had changed to a new owner. She was very pleasant and friendly.As I pulled my car into the open garage, I can see how clean and organized the shop was. She offered me a bottle of cold water and I sat in one of her cushy sofa chairs nicely arranged in her shop. She said it would take around 10 minutes to complete the test.Approximately 10 minutes later she had the results and explained the whole process of the filing of the smog test and completing the vehicle registration renewal notice.Darling is so friendly and personable. She made the whole process so easy. It is nice to take care of this vehicle registration requirement with NO STRESS. I will recommend Darling Smog to my family and friends.
