What can you do about a nonselling seller?

Just for the sake of clearity, I am the seller with my son Tigger 0063. The email came saying he wanted to buy and he asked what model, an Elite, Mk I or Mk II. That did not sound like a done deal to me. Now I have made an offer back to him to sell the only other one I own that I am using today in my system. What I get is this discussion?
The advise you have received here Lordgorian is to get on with life, I will email you later to discuss this further.

Zaikesman, I think your responce is right on. As you advise a full disclosure of personal info and a reiteration of the offer would help to clearify the intrest level. The biggest problem I've had here and on ebay is sifting out the interested "tire kicker" vs. the actual buyer. I've found 99% of the people I meet here are honest and come to the table with best intentions. It is hard however for all of us, from different backgrounds, and nations at times to communicate without flaw. This is why I offered to make good, not that a mistake was made, but that my communication skills may be at fault.
It would apear this situation may resolve itself. I thought by my entering this thread an education could be had, hoping to help others in the same situation.
