Because of the lack or very slow depriciation that the Prius has been seeing I don't think leasing is a good idea unless they are really cheap. The idea of the lease is that you only pay for the part of the vehicle cost that you use. If the car is worth 85% of its initial value after 3 years then the lease should have very low monthly payments. I'm not sure what the actual Prius depr. is but I know they have been selling at nearly new prices after a year and 15k mi. is put on them. (I just guessed at the 85% for illustration purposes) If they try to give you a standard lease like other cars have they will have you paying a lot more than the vehicle is actually depriciating. In this case you are better off buying and selling when your done.

Again I'm no lease guru...
