I was wondering if anyone has done this calculation yet? Has anyone checked to see how much money you would "lose" if you didn't keep the car after a 3 year lease and kept under your milage limit? I guess I'm asking if anyone compared the expected price you could sell your IS 4dr, auto in 3 years (saying it was a fully loaded one)to the amount you would pay for a lease what the average is now of 400/month with 2-3k down. I know this is asking a lot, but I thought someone may have done this calculation in deciding which why to go. I hear some people say you lose 41% of the car's initial price after 3 years. I know there is a lot of variables in this one.
