Acura tends to provide very large direct-to-dealer lease incentives rather than subvene the mf on their leases so you get big looking discounts but still higher payments.
I believe there’s around $9k in dealer incentives right now and you’re getting $1500 in loyalty, so $10500 of that $12k discount is incentives. That means you’re only getting about $1500 off, which is quite low.
You’ll want to head to their forums and find the 2020 mdx thread (or just search 2020 mdx lease Edmunds) and post, asking for the numbers for your trim/zip code/lease term.
Not sure why you decided to bump an older Advanced MDX thread when there are many base/Tech threads that are much more recent. Those would also be much more useful for benchmarking purposes.
