I went to purrfect auto service several years ago because they are located walking distance from where I live and convenient. I went in for a simple oil change and they called saying I needed much more service done, specifically an air filter for a $75 charge.
I told them to hold off on it for now and I will do it very soon.
Instead, a few months later I went to Big O tire out in Palm Dessert (visiting my parents) for another oil change and I asked them about the condition of my air filter and the service people at Big O said the air filter was in almost brand new condition. Purrfect will rip you off any chance they get.
