I'm mostly with the "Toyotas are tough" crowd and wouldn't be too concerned about 60 or 75k miles. BUT, as with any used car that's priced higher than your monthly beer budget, have a mechanic that you trust check it out for you before buying.
Anyway, but I'll give you my story and let you make up your own mind about quality.
1994 2x4 Xtra cab, 2.4L 22RE engine.
110k miles today, mostly town and country miles.
Measured about 27 MPG highway 2 weeks ago.
Parts replaced:
2003: starter
2002: don't buy a cheapo aftermarket thermostat, had to replace it again. Use OEM parts.
2001: timing chain (stupid plastic guides broke, so I replaced the chain too along with the oil pump and water pump since I had it all apart anyway).
2000: battery
2000: thermostat
1999: brakes pads/shoes
1999: spark plugs
1998: plastic unions for windshield washer hoses
1997: drivers-side rear-view mirror.
Just this year, the plastic latch for the rear sliding window broke and the plastic tailgate release handle broke. Grrr, plastic parts. Haven't replaced those yet. Danged 11 year old trucks anyway...
One final note, my truck drowned out in a flooded street in 1997... got a snoot-full of water. Water was in the cylinders (wouldn't turn over). I had it towed to the (not automotive) shop where I worked, removed the spark plugs, put oil in the cylinders and cranked it. Blew lotsa water out while I sweated bullets. Changed the oil that night and again 2 days later.
That incident had me worried that I was going to have premature engine failure, but at about 85k miles later, it's still going strong.
That's my story, for what it's worth.
