my experience so far has been very good... i got a 89 7m-gte motor... came w/ an auto tranny, full wiring harness + some other misc electronics, but it has about 19k miles on it (about 26k kilometers) i took it apart, re-built the head for security, and put on a new hg + arp head studs... only problem i came across was the block deck had 3 rust pits in it... we just epoxied it in and sanded it down for now, but this motor will never see much power, so it doesn't matter that much... it was $975 shipped btw
