fast but leaks
Sadly the market for cars like this is really soft. Most people would expect a bb or a hemi instead of a sb for that kind of money. It not having a heater or wipers kills it for street driving so that limits the potential buyer pool even further.
There is a buyer out there that will love this car when he finds it so it is just writing a detailed ad with tons of information as well as pictures then getting the word out. Do you have pictures of the body before the paint was done? Is the car rust free? All this information will help sell the car. Maybe get constructive with selling the car and take something that you can resell in partial trade since that will allow the buyer to fund the car easier. I have done that many times and it helps move a hard to move item.
