It depends on how the Honda Pilot sells in your particular area. If it is a top selling unit, then the dealership has the edge on the price. But if sales for that particular vehicle are sluggish, then you have the advantage. You can easily find out. Purchase something called "the black book", or hook up with a friend that works at a car lot or something.
Black Book
Basically, the "black book" is what 95% of car lots use to judge trade in/sale prices of vehicles. The dealership that I work part-time at uses it as well. I dont know the exact science of it, but the book is basically a car bible that shows the prices of cars based on your area. The book is also updated once a year to reflect on economic situations, inflation, etc.. They have it split into a couple different regions. (North East, South, Midwest, etc...) The prices are very accurate too. check it out and good look.
