I was wondering if someone could help me out???

I currently have a 1965 Pro Street Mustang that I am trying to sell. I was recently presented with an offer for a trade for a 1966 Fairlane 500 GT (numbers matching). The Fairlane is in good shape with some work that need to be done under the hood, just a little resto work and detailing maybe some painting and swapping a few parts out.

I am not sure the exact price either car is worth and from the sites I have been on, no one can really help me out. The '65 Stang is pristene, and has won several shows and placed in many others, I just really don't have time for a SHOW CAR anymore.

I am really only looking for some input, I know the ultimate decision is up to me, just need a little feed back please,
