I would question the hours, The nice looking combine I can see having 1200hrs that  other one about 4000+. I would think even with there disclaimer there would be something you could do, they didnt say that the seperator was messed up, they had pictures of two combines with yours being taken where it is harder to see the flaws, and third there was no contour master which they advertised.  I hope you come out on this deal ok.
