There are several debates about the financial sense of these kits, and the price differential if Toyota comes out with a PEV, but it seems everybody is overlooking the obvious. So I was wondering, just from installing a kit, what value is added to any Prius immediately? And what value would people expect several years later? I am most interested in the Hymotion kit, but it would be interesting to hear about the other kits too. I think people are writing off a key component of the financial viability of these kits by focusing only on money and gasoline saved, and overlooking residual value, and I was wondering what others thought.
