65,000 miles isn't a lot. I'm guessing that, since you've racked up
that much mileage in only 3 years, they're mostly highway miles.
Highway miles aren't as hard on the motor as city miles.
Proper maintenance is key. I've seen Camry's go over 200,000 miles. My
'93 -- a 3VZ-FE, not a 1MZ-FE -- has 135,000 miles on it, a fairly even
mix of city and highway.
