what to do if you have the "lost" car

I'm on the opposite side of this question. Long story short, I regretted selling a 70 Swinger 340, found it recently and spoke to the current owner. They are not interested in selling it and I respect that. I let them know I'm interested in buying it back but certainly understand them not wanting to sell it right now. They have my info and I check in with them periodically (every other month or so).

So my advice would be to tell him that you have all his information and will call Him first should your family deceide to sell it, but right now its not for sale. If he really wants it that bad then let him come to you, and your cousin, with a serious offer for it. Being a pest isn't going help him one bit.
