As for the costly secrets of hybrid cars, the first thing that is talked about are GMC's K15 Sierra hybrid and Chevrolet's Silverado hybrid. Many people would debate that these vehicles should not even be called hybrids.

The title is definitely misleading.

Speaking only for myself, there was no costly secret for buying a hybrid. Considering both the federal and my state tax credits, my Civic Hybrid w/Navi was cheaper by more than $1,000 than a Civic EX w/ Navi. This does not even take into account environmental concerns or fuel costs.
