Total price was $55 as reflected on their website. In today's world, where customer service is a lost art, it's refreshing to see a business where they actually care about their customers. I will definitely use them for my future needs and I highly recommend them.

I recently went to get a smog check because my registration was due and required it. I previously…read moreasked other smog businesses if they work with Dmv and they said no. I appreciate that this business does give Dmv the notice for pass. All I had to do was go the following day to one of those kiosk that have DMV and got my registration right away. Also they do get busy so I recommend going there first thing in the morning I was in and out in less than 20 minutes. Also go on their website to get a $10 discount that helps.

They told me the regular price but offered $55 out the door if I came right then, so of course I pulled up. The service requested was a smog check, and honestly this was probably the easiest one I've ever done. I was in and out in about 20 minutes. The quality of the work was great and everything felt quick, organized, and professional. Bella and the staff was super nice and friendly, which makes a big difference when you're just trying to knock out errands on a busy day. The overall service was smooth, honest, and straight to the point. No upselling, no surprises, just good people taking care of business. Safe to say I found my new yearly smog spot. If adulting had a fast-pass lane, this place would be it. Highly recommend.

I personally smog all my cars there and all my family does as well. Try them out, you won't be disappointed. I drive past many smog shops to get to them.

Today I was completely blown away by the level of service that I received from SpeeDee Oil Change…read more I was greeted by the nicest gentleman, Mike, to later find out that he is the owner of the location. He immediately made me feel super confident about the service that was going to be performed on my Audi Q7. His entire team was very attentive and gave me a feeling that every employee here had a sense of pride to be working with Mike and his team. They even were able to reset my annoying inspection required light that I thought only the dealership could reset. They completed my service and had me back on the road in a very timely manner. The value of coming here for a routine oil change compared to going to a dealership showed me that I have been throwing money away in the past. Not to mention the amount of time a dealership takes to make a simple oil change seem like an engine overhaul. This is my family's go to spot for a premium oil change with the confidence that Mike and his team will take care of our vehicles like it is one of their own!
