So I am new here, as I said elsewhere, and am looking at buying a 1975 Plymouth Valiant. It has 519k on the Slant 6 engine (225HP I believe), and the bottom of the trunk is almost rusted out from where a weather seal broke. She has been her in the South for her whole life, and the current owner doesn't like to do body work, which is why he is selling her. He wants $650 for it. Is she worth it?
