Re: battery replacement
I'm not sure of the cost, but the battery should last a long time (10+ years). I wouldn't put a mileage number as the replacement time as time itself will tell you when to replace the battery. There are older hybrids (Insight/Prius) that have logged over a million miles on the same battery pack. If you do a search for Vancouver Taxi, you'll find tons of high mileage hybrids (escapes included) that still run on the original battery pack. When replacement time does come, I'm sure it'll be cheaper to trade the vehicle in instead of getting a new battery pack installed. Once you factor in depreciation and wear and tear you'll probably spend more money than what it's worth.
