Bought a groupon for oil changes... took car in early on Saturday when they don't take appt's. left car an went shopping, 2.5 hours later they hadn't got to it yet.  \n\nRescheduled for an appointment time and when I went in, they were 45 min past appt.  They asked about changing air filter, I told them \"only if it is in stock, I can't wait any longer\" and they ordered it anyway and made me wait while it got delivered.\n\nOnce they DID finally get my car in, they did good work and even showed ME how to change my Passenger compartment air filter.\n\nI'll know better next time to just leave car all day:(
