About 277,400 on my '96 SR5. Manual transmission was replaced by the PO at about 210k, and I've replaced a ton of stuff including both diffs. But the engine is original.
Man, here I am worrying that i'm dumping too much money in mine for maintenance, and I'm sitting here with 180k miles on the odo. I guess it's safe to say that the old girl should have another 100k easy to go.
Sure she's got some rust, but norhing I think I need to worry about for at least 5 years methinks.
