I got the following quote from a NY dealer: $245/month for 3 year/12k lease or $259.20 for 15K lease on Prius II, with cargo mats and nothing else. Money factor is .00001 and residual percentage is 65% or $15,496. Selling price is $21,008 and MSRP is $23,840. I tried to calculate the monthly payment but I come up with $164.75 (not sure if I am including everything). My tax rate is $7.35%. What information as I missing.
I've posted (several times) an excel spreadsheet that calculates lease rate. The input section shows all the important variables. Try a search if your interested.
