with under 100k and its tested for compression and making sure everything is running perfect at running temps. plus a video of it running, and with it being so clean i highly doubt a salvage motor would be any comparison. Salvage motors arent as reliable as this deal, at least with this deal i see it running hear it running see all diagnostic tests done on it and know for sure that its in great condtion, with salvage motors you dont know what they need, plus they dont usually come with all accessories and are in turnkey condition, to top it off you dont know if the salvage yard is gonna screw you over on the warrenty and say its a user issue if something fucks up
