We may be getting a change of mind on this car--currently on the waiting list for a 2005... Is anyone aware whether the 2005 will have added horsepower? I accidentally high-centered my (work) Prius today while trying to back down a steep and serpentine driveway. With one wheel over the curb, it did not have sufficient horsepower to move forward from that position--like a standard auto would have. Had to get the help of neighbors to carefully back the car down a raised platform of planks supported by cinder blocks until the curb height was reduced enough for me to proceed forward and back down to the road. I also have noticed that the car can barely back up a steep driveway in reverse. Are you aware of any improvements in this area? Thanks!
