Loved by Pasadena Drivers
Don't just take our word for it. See what our customers have to say about our fast, friendly service.
"I would highly recommend this place to everyone! The gentlemen working was very accommodating given it was an extremely hot day. He made sure I had shade and the fan with the mister was blowing on high…"
"The owner helped me out. I was in and out within 10-15 minutes, tops. Easy peasy, lemon squeezy! 🍋👍🏾😊"
"Quick service. I went on a Tuesday around 5 and there was no wait. They have a few chairs outside for you to sit while you wait. Paperwork was explained perfectly."
"I had a good experience. I didn't know that changing your battery right before the test would cause it not to pass. He asked me about it and then told me to drive it for a couple days and bring it back. He didn't charge me at that point. When I did have it done is very quick and professional."
"Luckily I went there in the afternoon and there was no waiting time. A small bamboo booth with water mist was provided to dissipate heat. The test is fast…"
"Dropped in, he did the test without delay, and that was that. Thanks!"
