The jury is still out on that one. It still looks like you lose though.  It
takes allot of miles of driving to make up for difference in cost between
the non-hybrid model and the hybrid one though the more gas costs the sooner
you will realize your savings. Other problems are the hybrid depreciates
really fast because when that car is out of warranty next owner will have to
pay for the replacement batteries, the $7,000 variable transmission if it
breaks, etc.
