Hang on: tire rotation at 6 month/6000 mile intervals is included in the service plans.
And, if you live where it is cold in the winter, and away from a service center (for example, we in Utah who are 500 miles from a service center), they will replace the 6mo/6k miles tire rotation with swapping your winter and summer wheels 2x a year. If you get service with unlimited ranger service, this covers the swap and the ranger fee. So, you get the annual service, and swapping tires 2x a year, plus the ranger at your house 2x a year, plus any other time the ranger needs to come, all covered under the plan. Makes the 4 year or 4+4 year service with unlimited ranger visits quite a cost savings package.
