I messed up on my registration and failed to notice that I required a SMOG check. Imagine my…read moresurprise when I opened the letter from the DMV expecting to see my registration, but only seeing a notice. I read the DMV letter in December. My registration expires December. Enter panic mode. I started looking for places to do my SMOG test. I found this place. I called and was informed I could do a walk-in, which I opted for. I asked how long it would take, and the man quoted me 10 minutes. I waited there and watched the process since I've never had to do it before and was curious. I watched him hook up the machine to my car, but became distracted with a call. By the time I hung up 10 minutes later, my car was done and PASSED (anxiety levels declined). I paid in cash since I know a lot of small businesses prefer it, and I'm considerate of that. Thanks SLTO!

I'm glad I checked because sometimes Groupon can be cheap but it usually doesn't include $8.25 certificate fee and $1.75 electronic transfer fee, so you end up paying more than you thought you would. I walked in on a Saturday around 1:30pm without a reservation and was in and out within 10 minutes. The gentleman was friendly and efficient. I'm so glad I found this spot and will be coming back for smog checks in the future if the price remains the same or reasonably priced! They even had a TV inside while I was waiting!

This is the type of establishment where the life of the customer is considered and paramount -- the work is executed expeditiously and you let go to return to living it. I will return to this business in the future.

Once he determined the issue and the parts needed, he placed the order for the replacement parts and I put the deposit down. Parts arrived next day and I was able to bring the car in during my break. Within a few hours, my mirror was fixed. Additionally he noticed that the air in my car smelled funny, he asked if I wanted my cabin filter changed. I took him up on the offer and he quickly obtained the replacement parts and had it ready within the business day. Communication was great throughout the process and all questions were answered. He was friendly and professional. Repairs and service were completed so quickly, I barely missed a beat! Fast, reliable, friendly , would come again!

I had an excellent experience at Pro Smog with Dan. You can immediately tell Dan is a true car guy…read morewho genuinely cares about the vehicles he works on. He treats customers' cars like they're his own, and that level of care and attention is hard to find these days. His shop is always busy, but now I understand why -- customers keep coming back. You see a steady flow of returning customers and it's clear he has built his business on trust, honesty, and word of mouth. In fact, that's exactly how I found out about Dan's shop -- everyone in town seems to know about him and recommends him. Even though he was helping other customers, he acknowledged me right away and was very professional, friendly, and honest about the wait time. No surprises, no runaround -- just straightforward, honest service. The process was quick, smooth, and very reasonably priced. Excellent prices, great service, and a very honest owner. Dan is approachable, professional, and clearly takes pride in his work and his business. It's rare to find someone who is this honest, efficient, and friendly all at the same time. I highly recommend Pro Smog. There's a reason this place is always busy -- good, honest service and happy returning customers. I will definitely be coming back.
