Yeah, I bet most dealers (mine included) are pretty clueless on these cars.
When I made the decision to purchase this car the math was pretty easy - at $20k after rebates and incentives, and ~$0.03/mile for electricity, the total cost of ownership is $0.23/mile (plus tires and vehicle registration, insurance, etc), IF you drive the car 100k miles and then scrap it at zero value. Scraping the car at zero (or near) zero value at the end of life seems pretty likely at this point...but the 100k mile figure may have been optimistic. My car is ~4.5 years old and only has ~35k miles. I know the battery warranty is 10 years/100k miles, not sure if that applies to the rest of the electrical drive system. But even if it does, looks like 10 years is going to come before 100k miles in my case.
