If you are really interested, knock on the door with cash in your hand. Without seeing the car or knowing the facts, I am sure you cannot estimate its worth, or know if you even want it, but cash definitly changes a person's frame of mind. This is a fact.
A gentleman wanted 25K for 67 convert I bought last Nov. When I pulled 4K out of my pocket and told him I could have another 13.5K to him by the end of the day, he didn't even negotiate. I picked up my # matching, 67,000 orig mile roadster for 17.5. Give it a whirl.
i knocked on the door as soon as i saw the car. but the people in the house either do not speak english or they do not want to talk about the car. i ask about it for about 5min, but they looked at me with a blank gaze. finally i tried to get the woman out side, but she just looked at me and replied "no for sale". i left my business card and off i went. i drive by it pretty much once a week, the car looks pretty rough. the only thing i can tell for sure is that it has side pipes, knock offs and it is dark blue. actually there are a few more vettes in my hood, i will try and snap some shots and post them.
