That's exactly right.
We were not happy with the Oak-Tree Mazda service. Multiple service issues, e.g. like overfilling oil, not answering their phone, needing too many unnecessary appointments and more. In the last visit, I found out that they never checked the cabin air filter. AFAIK, it is probably the original, as it was not covered by the plan. What piece of mind do I get with "full circle" inspection, knowing they failed to check the filter? What other things did they fail to check?
However, we were a captured audience, all other dealerships in the area will require us to sit in traffic to get there. We take the other cars in our household to a local mechanic, which is honest and does everything quickly.
I will likely replace the CX-5 next year. Coming back to Oak-Tree for service, even only for warranty work, just gives me the shivers. A good enough reason not to get a new Mazda. On the other hand, we have 3 Honda dealerships all within reasonable distance, even more if you are willing to drive longer.
We did not finance the car. However, prepaid maintenance means you finance Mazda / give them a loan, which they return to you over time through service they provide to you.
We used up almost 5 years worth of this plan, so I don't feel that bad. However, I do feel cheated for getting a non-comprehensive plan with no paperwork, which was a simple bait-and-switch scam on the part of Fremont Mazda. Promising one thing then selling you another, then hiding the facts, by providing no plan documentation.
