Keep in mind that the batteries for the hybrid drive system can only be charged/recharged so many times (warranty is 100,000 miles or 8 years, whichever is first, 150,000 miles in California). If this car is getting close to that time, then YOU will be stuck with the replacement costs or a non-functional vehicle; Approximately between $2500 and $4000 plus labor costs. Contrary to popular belief, the do not last forever. If the car is driven beyond the minimum 40% battery charge (if the computer control has been bypassed), it will reduce the battery life greatly. How can you tell if the car has had that happen to it? Impossible to tell, and I'm sure the owner will not reveal this to you; they're trying to sell the car! You may luck out and find a battery in the junkyard from a wrecked car, but still not as good as a new battery. Buyer beware.
