So, I think I am getting closer to sell. I have owned a 1960 Buick Invicta coupe with a custom bucket seat interior since 1975. My dad and I pulled it out of a junk yard and did an amateur restoration. We did change the color from beige to red. I drove it for 5-6 years and it has been parked ever since. The motor has not been started for that long either. The body had lots of rust in it, which we did a very amateur restoration, but it is all there. At about 2000, I decided to re restore this car, only professionally. I found a rust free lesabre coupe (then) shell in Colorado with factory a/c but no drive train. I also found a very rusty lesabre 2 door sedan with 20k miles but perfect interior. Then when I was about to turn all of that over to my body professional, I found a completely rust free Invicta in Idaho. It did not run, but was very clean, no rust ever. Interior was redone but not to stock. So I bought it, got it running, and left my project sit. Long story short, too busy with work and life and now all four cars are sitting. The Idaho car still runs and drives well, but the tranny leaks. The other three cars have not moved for 20 years and have been stored in an old lumber yard. A local guy would like to buy the Idaho car, but I told him it is all or nothing. Where can I find some sort of guide as to the value of all this? He wants a number. BTW, not interested in parting it out.
