The onlly tip I have is to check to see what their milage restrictions are. There was a dealership I used to work for that would sell them and if the customer was a small amount of miles below or above the service interval they would not do it under the agreement. I remember people getting yelling mad in the service drive quite often as they'd be 100 miles past whatever interval it was supposed to be and they'd have to pay out of pocket.
