You can share with them that you are not sure if the car will pass smog and they can try to do a few basic things to gauge right off the bat which we appreciated. Other places may do re-test for free if you do the initial smog check with them (but possibly higher in overall price) so keep that in mind.

When the EMT asked if "All good then?" I looked at Ara to see if I passed my SMOG and with the affirmative, answered "Yep! Good to go!" His customer care goes above and beyond and you just don't find this everywhere these days. I found him in LaCanada years ago and followed him here to Pasadena and as busy as he was, I see he is no longer the best kept secret haha! Thank you Ara for your kindness.

The two previous places I got these done seem to be no more, so I decided to try Vista Test Only. I am very happy with my decision. First of all, it was like 100F out, and the owner Sam handed me a chilled bottle of water. Then, some chocolate. Then some walnuts. He also brought over an air conditioning unit and pointed it right at me. Wow! He was also extremely friendly and seemed to genuinely enjoy talking to and learning about his customers. He even helped he find a place to grab lunch after my test. And if all that wasn't enough, he also charged less than the other places I called up. Next time I need a test, I'm definitely going back to Vista!

The service was amazing, incredibly friendly and quick. I called in to see if they had any availability, and said to just come on by. Of course, in the 5 minutes it took for me to drive over there, a couple other customers got there first haha, but all good I really didn't mind waiting a bit. I can't remember what I paid, but I know for sure it was the best deal compared to all the other smog check businesses that I called. Both my car and my wife's car have to be smogged every couple years due to their age, so we'll definitely be back here soon. Thank you so much! Truly the best 5-Stars all around.

They also checked my oil and topped off (I was extremely low). Today I came in to ask a question about my oil. They noticed I was past due on my oil change and said we could take you now and have you put in an hour. This would have never happened at my old mechanic. To be seen by them you have to go first thing in the morning leave your car and hope they call you same day to say it's ready for pickup. I would definitely recommend come here. Fast efficient and worth your time.

I called ahead to confirm if they could make time and we agreed on a date/time that worked. Upon arrival, the shop was jam packed with tons of cars. Feeling a bit worried that my check up would take forever, they quoted me about 1.5hrs to do the standard checks including brakes, tires, fluids, and oil change and it actually ended only taking 1 hour! Very thankful that they were able to squeeze me into their busy schedule and take care of my car efficiently with friendly service! They've won me over and I'll definitely come back again in a few months for the next service date. What's also great is there are a lot of pretty decent spots to eat and even a few nice bakeries too while you wait for your car to get serviced. Highly recommend giving them your business!
