Sorry to hear that man....

At the dealership I work at, Im in sales, if you buy a NEW vehicle and it needs any type of service.... Be warranty work or an oil change, we provide a FREE rental for the first 3years or 36000 miles.

For used vehicles its alil different.... Depending on the type of service contract or extended warranty you buy, you may or may not be eligible for a FREE rental. But we try to help out our customers as much as possible....

Dealing with the FREE oil changes from the financial manager.... Well Ive never heard of that before. Either the owner of the dealership approves that or not. A manager cant do that.

With the windshield wipers, unfortunately, service departments will do that.... Anywhere pretty much. They try to make money anywhere they can.

Sorry to hear your bad experience, but not EVERY dealership is like that....

Definitely make a call to the owner.... He'll get it straight for you.
