I went to this location because I have been to other Purrfect Auto locations before with satisfaction. However, I came to this one to get a smog check and right off the bat, they informed me that they couldn't do it because I didn't have the carb# decal/sticker for my Comptech Supercharger which is carb legal in CA. So I get it, they didn't want to risk their license or business for that matter. But they could have checked the information on the Air Research Board where they would find the information needed to input into their system. They were just too lazy to do it and insisted that I get the sticker. They charged me just for looking under the hood for less than 5 minutes and told me to come back when I got the sticker. I went home and called the manufacturer, CT-Engineering in Norco, CA, and spoke to the owner, Nate Heinz, who told me that he would send it right away. I got in the male a few days later and it was a simple sticker that I placed on my supercharger unit. I brought the car back and again, they said they couldn't do it because the sticker was not enough. They asked me where I got the sticker from and I told them the manufacturer and they could call them if needed. I also brought the executive order for the unit and they didn't even bother looking at it because they said that the sticker was not matching. After about 10 minutes or so, Dave the front desk guy came back and said that he would also have to check my header which is also carb legal with the decal welded on there and I asked why. He said that it had to be checked to make sure O2 sensor was installed correctly. Well if it wasn't installed correctly then it would throw a check engine light and there were none. He then said he would have to put it up on the rack for inspection and he would then have to charge me labor time and wait about 3 hours. Bullshit! They just didn't want to do it and lacked the experience/knowledge to do so. I left angry and frustrated. On the way out, I saw another smog station next door and decided to go to them. They performed the diagnostics with no trouble and the carb numbers matched just fine. They performed it in less than 15 minutes with no hassle. I even got a free car wash. This location did not meet my expectations and did not perform up to par as other locations.
