Yes, not happy. But them the breaks I guess. I have been in the same position in the past, agreed on a price etc, had someone offered more later, but always stuck to the orginal buyer.
They seem like nice people, but just didnt want to bother pulling trailer out of the shed at the moment. When I asked about date of manufacture etc they where a little vague. I understand this, sometimes I cant remember what year something was built etc. However they told me they couldnt even get to the VIN plate, to much clutter around it.
I am sure they are genuine people, but I didnt really want to pay the full amount with out seeing picture of VIN plate and getting the dates etc.
