I have a friend who loves the challenge !
Shops for cars on rainy Tuesdays, two days before the end of the month (especially if it is the end of a quarter), etc. He goes in knowing what the dealer inventory is (by visiting the lot after closing the week before) and the dealer cost of the cars (online research).
He tells them the price he will pay and has walked out on several negotiations. They call me and ask him to come back.
The best one was a lease several years ago. zero down, no first month payment, no last month payment, no security. He signed and drove off the lot without a penny out of his pocket !
