Bought my 1992 Camry about 15 years ago and have been really satisfied with it. Few major mechanical issues over the years - most of them self induced (e.g., too hard on the transmission). Still runs great after all these years. Expect that it will run for another 50,000 miles. Consistently get 20 mpg.
Bought my xle v6 with 60,000 in 1994. It now has 270,000 and in that time have changed brake pads 3 times, CV boots twice, wires and plugs once, two timing belts and struts and other that filters, tires and oil.... That is it ! If I could buy this car new today, I would. Best car I ever owned (I am 60 years old).
I was surprised with all the trouble I had with it. I had to replace the rack, water pump, and radiator. When I managed to get rid of it, the heater didn't work and I was still having problems with the car overheating, there was a major leak in the air conditioning system, and the AT wasn't shifting well. I suspect that a previous owner must have badly mistreated this vehicle (and possibly rolled back the odometer), though it's possible Toyota occasionally produces an individual lemon.
Comfortable car that handled well, even though the ball joints were also bad. Solid engine.
Given that the car I had may have been an anomaly, there's nothing I can suggest.
Bought the car new,it is a 4 cyl.
Changed the oil every 3000 miles,
timing belt every 100k and usual
maintenance items. Still has the
original engine, trans, etc. Has
always been reliable, passed this to my
son. Wife has a 96 with 110k, again no
problems. Recently bought a 2000, hope
to get 200k+ miles from this one.
