I'm disappointed to be posting this review. A few months ago, I went to get a smog check. The old gentlemen explained that he could not get a reading, drive it for about 150 miles and come back. He charged me $50 but said he won't charge when I come back. Fast forward a few weeks ago I go back after doing what he said. They claim they ran it 4 times but could not get a reading. He said something is wrong with my car and to bring it to the dealer. So I went to the dealer, they said nope, we can't touch your car because it's exhaust related. You would think quality tune up would know that? Anyways, I'm stuck but decide to go to another smog place down the street. I explained my predicament and they were able to run and pass my car in 10 minutes - no issues. I then googled Quality Tune Up reviews and found almost identical situations to mine. This other smog place said they are either running a scan or don't have the right equipment or knowledge. Here is where I'm really disappointed. I've gone back to Quality Tune several times to speak with the owner, only to be told he's not there. I've gotten no call back or response. I'd like a 100% refund on the smog I ran with them. It would seem appropriate considering the runaround I've been given. I've also been a loyal Quality Tune Up customer for many years so you'd think this is a drop in the bucket for them. We live near this Quality Tune Up but have hesitated to go because we visit the one on Winchester that does a great job. But out of convenience, I decided to give them a shot last Saturday morning. I'm glad I did. The workers and manager are very friendly and knowledgeable. They made suggestions based on the card performance and stated certain things were not needed to save money. They were very quick and called me as soon as they were done. I would definitely go back and recommend others as well.
