Its not so much the mechanicals today, its the electronics and when our Honda CRV had issues and they were resorting to changing expensive parts with no end in sight and no guarantee it would be fixed and the OB2 dealer readout did not pinpoint the issue, that is when we said enough. Our next new vehicle had the extended warranty. I have no issues paying for a new transmission on my Tacoma pickup at $4000 plus and I replaced the spark plugs and serpentine belt last summer. I have always worked on all my stuff, never took ever to a dealer. We did switch over to all Toyota and my Tacoma will be replaced with another.
