Many people buy a service contract because they want a repair budget that behaves. That is a real worry, but it is a different worry from the fear of a single large breakdown. Before you compare any list, decide which worry you actually have, because each one points to a different answer.
Make the two lists side by side
Open the owner's manual and copy the maintenance schedule onto a sheet of paper. Oil and filters, fluids, belts, brake pads, tires and the other items with set intervals belong on it. Then, on a second sheet, write the repairs you have actually had on this car, or on similar cars you know well, along with what they were and how often they came up. The first sheet is the planned part of your spending. The second is the unplanned part, which is closer to what breakdown contracts are built around.
Tell whether you have the problem
You likely have a budget problem if most of the planned sheet is what worries you. Scheduled service is predictable, so setting money aside on a fixed schedule may suit it better than a contract. You likely have a breakdown problem if the unplanned sheet holds the surprises that frighten you. That is the situation where a contract's waiting periods, exclusions and claim rules deserve close reading. Many households have some of both, so write the split down rather than guessing.
Ask the questions the split raises
Ask the provider whether any scheduled maintenance is paid under the contract, and if so, which items and under what conditions. Ask whether you must keep service records, and in what form, to keep a claim valid. Ask whether a waiting period applies before breakdown coverage starts, and what that period is measured by. Ask whether the contract's terms change if the car is serviced somewhere other than a dealer. Each answer should come from the written contract, not only from the sales desk.
