Supermathis,
Your question was:
"Do you think the Prius potentially may have more (Variable )maintenance or repair costs as compared to non-hybrid civic? Maybe as a result of the additional Hybrid system."
My answer is:
I don't know. It depends upon how long you intend to keep the vehicle, and how long the warranty protects you from these unwanted variables. The "hybrid" is still a fairly new vehicle, so it is hard to judge long tem costs.
There must be a few people on this site who can give us some data to crunch.
