you should stay clear. I would honestly be more fearful if it was from a dealership. Couple of reasons is that they got it at a steal of a price and are actually just going to turn it around as is (whether that is disclosed or not), another reason is that they wouldn't really be knowledgeable about the Z in order to be concerned nor care what needs repaired or replaced and you can guarantee that won't be disclosed. Best bet, is to troll the classified here and find a Gem. They come up for sale more often now than you would think. Then just review the sellers post history both in General forum and Technical forum(most importantly). Just my 0.02. Good Luck, Dre
