Market reality has finally stepped in on the MDX.
I have a base '03 MDX that I leased in November, 2003.
At that time residual for 48 months was 59% (for Touring 3% less) and money factor .00225 (5.4%)
Your money factor is .0022 (5.28%) Shop around, you might be able to do better.
Even though this is April, the residual have dropped by 5%. But this is more in line with current resale values. In fact, I doubt your '04 MDX will be worth 54% of MSRP in 4 years!
All the more reason to lease! Take advantage of that high (read factory supported) residual!
