If you are going to go with
If you are going to go with What-Ifs... I would say your odds are better that a major engine/tranny problem would happen on the Ford vs a Prius battery problem, and thus, it would be a wash.
I dont want to come off as a jerk to the writer... But this whole article comes off as a Ford dealer sales piece. I would verify some of the other items on the comments thread and re-write it. Then, use this kind of information on future reports.
Just a thought.
