There are a lot of people here who know a lot about leasing. Feedback seems a little noisy for a first timer.
My advice is to poke around on the website a bit. Specifically use the search function and look at recent MDX threads. It all depends how much your time is worth. Spending a few hours here should save you a few grand. Past that, you save less per hour of research.
Good luck.
The $8500 is on the Technology package. The lease cash on the base model is only like $7500.
MF * 2400 = annual interest rate
(Net Cap Cost + Residual Amount) * MF = monthly interest
(Net Cap Cost - Residual) / Months = monthly depreciation
Keep in mind that the MF monthly interest calculation is just a shortcut to the monthly payment and the actual lease amortizes like any regular loan (i.e. more interest early on with increasing principal portion as time passes).
This is the best that I could get so far:
MSRP = $47695
Discount = $10156
Cap Cost = $37539
Tax = $190
Bank Fee = $595
Dealer Fee = $536
Total Price = 38860
Drive off out the door = 2746
monthly = 409
