Hi, all. I have a friend who has an Audi A8 with 3000 miles on it. It's dark blue with black leather and in mint condition. It's been garage kept its entire life and he wants to sell it to me. He is an avid car collector and is wanting to make room for another car he just purchased. Question is, how much is this car worth. KBB says 2900 but it's practically new. No one has ever even sat in the back seat. It has the 4.0 liter v-8. Any advice would be greatly appreciated.
