Pricing Help

Truth be told, I'm a newby to the world of MOPARS. I have an opportunity to pick up a 69 Barracuda convertible wit a slant six. The body is in great shape...no rust. I believe it received a restoration about 12 years ago but I don't know the extent. Not sure if the engine received a rehab. It will need a new interior and the top has a rip. Other than that it looks to be a great weekend driver. Here's my quandry, what is a car like this worth?
