Horrible service time, made a appointment to have a oil change done and we were there for almost 3 and a half hours, service writer did give us a $10 discount, but when we were leaving I noticed a banner hanging in the service bay area with a 1 hour service guarantee or iits free written on it, maybe there was some fine print we missed, but over 3 hours for a oil change with a appointment seems excessive.

Update! I received a call from the service writer apologizing that they had made a mistake and that they will stand behind their guarantee. With that being said, I'm giving them 4 stars now as any businesses can make a mistake, but they made it right and I've never had any issues on my previous visits.
