I'm in the market for a newer vehicle. A 2006 Ford Escape hybrid AWD came up. I'm not looking for reviews on this particular vehicle per se, but for input/experience on buying hybrids used. The majority of our city taxi cabs are all hybrid Priuses We have a fairly good public auto insurance body that dictates all used vehicles be sold with an up to date "safety." This is just a general checklist that makes sure the basics are satisfactory (engine, exhaust, trans, lights, brakes, etc) So...this part I'm not too worried about. This particular vintage is 6yrs old. What might I expect regarding the life expectancy of that big honkin' battery? It's not like I can simply chuck out the old one and pick up a new one at Wal-Mart..at least not yet LOL. I read somewhere that Ford (not sure if only applicable in the States) warranties the battery for 8 yrs, which would give me up to two more years, and then I guess all bets are off.
