First visit since they switched from Kachina to Desert Cadillac.  Also will be my last visit!!!  Very disappointed with bait and switch in the service department.  Went online to book appointment for an oil change.  They had a coupon for $39.99 (which I thought was kind of high) after I dropped of vehicle and was in the waiting room they came in and told me the oil change would be $100 plus and that they would Not accept the coupon from their website.  If you need your Cadillac serviced go somewhere else!!!
