USAFANG67 Posted: 7/24/2011 10:48am PDT How do you convince someone who is looking for a used car that they should consider buying a Hybrid when they know the battery warranty is only good for 100k miles. Especially if the use vehicle say has 80k miles on the OD and know that replacement cost of the battery bank is in the thousands of dollars?

Driver and rider acceptance will also be evaluated. Good for Ford to continue to do the time-honored thing that GM downgraded (GM killed their durability testing).
