if i'm not mistaken, Honda doesn't allow more than $1k-$1500 markup on their cars... but like i mentioned this doesn't apply to "limted edition" vehicles... the dealers does what they want with those...
Let's see if I can help set the record straight on this issue. First off, full disclosure, I work at an Acura dealership in Hawaii. We put $3995 of dealer markup on every car. But I can't think of any time in the last few years that anybody has ever paid it (or even a part of it)
Bizzy, as for what Honda allows, as I stated before, they have no say in what the dealership does once they get the car. However, they can (and do) limit how much they will finance over the sticker price. This is typically expressed as the percentage over the sticker price and this allows for a dealer to "un-bury" somebody who is upside down on a trade-in. This might be where you have gotten the impression that Honda has "rules" about pricing, but they do not. Only rules about financing.
So the question is; if you've never charge the dealer markup, why add it at all? While I cannot speak for other states, I can say that in our state we're not allowed to raise the price (above the posted price) for different customers. This means that we have a difficult situation when somebody is "upside down" on a trade. So, the dealer markup exists because we can always lower the price, but cannot raise the price (on an individual basis). Anyway, I hope this helps clarify what Honda allows or doesn't allow.
