This is not my vehicle. It's interesting how little maintenance has been done and it supposedly "runs great". I prefer shorter fluid change intervals which doesn't add much to the cost of ownership.
Original transmission fluid ... no slipping.
Differential fluid replaced twice ... no grinding.
10,000 mile oil change interval at Toyota.
Original suspension and bushings.
"... would be nice if front dampers were a little firmer."
Alternator replaced ~250,000.
Replace windshield one time.
Still gets 18-21 MPG at 310,000 miles.
$41,000 spent on fuel and he hopes 6th gen Trail will be a hybrid with 35+ MPG.
