I am currently in the market for a used or certified pre-owned Honda
Odyssey. Options on the minivan are less important for me as long as
the target minivan is value for the money.

If the dealer price is $24K on a certified pre-owned Honda Odyssey,
what should be the floor and ceiling prices of my negotiation?

I am thinking:
Floor price: $14,400
Ceiling price: $16,800

Agreed wholeheartedly that Honda Odyssey is a great vehicle with proven
quality and reliability.

But purely from a negotiation standpoint, am I being reasonable? My
current position is to walk away from the deal if I cannot achieve my
BATNA (ceiling price).

Thanks for any candid feedback.
