From what I've learned, 25% is a great deal. 30% off is an incredible deal. 31% off or more you should write a check before the dealer changes his/her mind. I was better than great-deal. Not quite an incredible deal. I was buying a boat that (my hunch anyway) was coming off floor plan end of July. I closed on July 25th. Good for all involved. And I didn't grind the dealer in to submission. I want them to be around for service. So...better to appreciate everyone has to make some money.
