I dealt with that a lot when I was trying to find my new engine here on RJ. I had money in pocket ready to buy every engine I inquired about if it was built right. but some sellers didnt even bother to take a single pic for me... I am not going to buy something like an engine without some proof of its existance. I understand that there are a lot of tirekickers out there, but all it takes is one serious inquiry to make a deal go through.
I was patient and now I have the perfect engine that I was looking for. Thanks RJ!
