Porter Valley Test Only is a small, single garage smog testing facility located just off Balboa Blvd in Granada Hills. The location is tucked behind a row of automotive shops, which can make finding it for the first time a challenge, but it is well worth the effort. Testing is quick, efficient, and reliable, with an average wait time of under 30 minutes. The facility is STAR certified and offers a fast, while-you-wait smog check for all vehicles, including diesel, out-of-state registration, and DMV renewal. Service is consistently described as top notch, quick, simple, and friendly. Prices are reasonable, and a coupon for an extra $10 off is available. The overall process is painless apart from initially locating the garage, which is accessed via a narrow alleyway. Customers highly recommend stopping in for this fast and reliable smog service.
Very friendly, honest and quick service, it takes about 15 mins depending how busy it is. $10 coupon available online, you pay $60 quite reasonable! Highly recommended!

The mechanics are nice and approachable. The pricing for the repair is reasonable. I feel comfortable going to this shop, honest pricing and they only fix what is needed. Compared to the dealership their prices are a lot cheaper. Honest mechanics.
