Was this one of those instant chat things? not a forum? Cuz seems to me, if you caught her bluff, she could easily leave. That way shes killed the topic of discussion and if you ever saw her again she could claim she got thrown offline.
Anyways, it may be that she infact doesnt know every there is about cars. Not only that, but knew nothing about hers. Typically if anyone knows anything about cars, its the one they own. I'm wondering if shes the original owner. Its quite possible that someone may have lied to get a better deal. So she may believe that cars real, because of what she was told. And its much easier to believe someone on the net as being a retard rather than someone you've exchanced large amounts of cash with.
Also, it could have been a misunderstanding. If I were to make mine into a replicar, or poser car, and turn it into an indy pace car, THEN sell it. Telling a possible buyer that only 1000 were made they may ignore whatever I said about "replicar" or the fact that theres a v6 in it.
Fact is she said only 50 were made. 50 that were white coupes with tan interior, cd player, this option, and that option, it IS possible to make your production number low. Besides one of 50 doesnt sound like something that would be a daily driver. And whats the point of owning a car if youre never gonna drive it?
