I tend to go along with the rest of the gang here. My example will be based on my '66 Grand Prix. When I bought it, I told the wifey that it would be one to sell and profit from. I put a sign in the window and an elaborate list of attributes, with a high price. This was to satisfy the the wife's thirst to sell. We drove the car a long time and had a lot of people thinking I was nuts, then someone saw it and had to have it. I tried every way in the world to convince this girl that she didn't need a project
like that, but she was determined and paid my asking price.
I miss that old car like you wouldn't believe.
Point being, IF you have the time to find them (or them find you)
there is SOMEONE out there that is looking for a car like yours.
The other side says, don't sell if you will regret getting rid of it. I miss old GrandPa somethin' awful.
