The whole thing makes no sense to me. First OP says the owner refuses to sell to him because he can't afford it. OP claims to add parts to a car he does not own in the hopes of selling it to make a commission, why add parts to something you don't own and have no contract with the actual owner to sell the car? Then the OP claims it is on ebay with no reserve and will sell for whatever.... How does that make sense, why not buy it for your original offer price and claim that is what it sold for?
Then the pictures, it was found in a foreclosed house basement that was so covered with plants you couldn't see it. Then the picture shows it outside of of what looks like an industrial garage area? Then, more pictures show up in a nice photo shoot style parking garage setup? If you want to have more fun, open the pictures in a text editor and look for dates. I clearly see 2007:10:13 . It is either different cars or someone forgot to set the date on their camera but that is an oddly specific date for a camera to default to and the same info does not show up in the first picture. It would also be very strange for someone who doesn't own this car to be driving it around using a plate belonging to someone else and for a different vehicle.
On top of everything, who is to say the person on the phone the OP talked to is the actual owner of the car? When someone wins the ebay auction who will handle the sale? Will the auction winner be given a phone number to call or will the OP handle the transaction and hope the sale is legit?
