There is not enough comparable history to draw a useful model-year comparison.

Counts are not adjusted for sales, age, mileage exposure or reporting. A lower count does not establish that a car is problem-free.

WATER PUMP GASKET WAS REPLACED AT 65K MILES, HEAD GASKETS, THERMOSTAT & RADIATOR WERE REPLACED AT 78K MILES AND WATER PUMP CLAMP/HOSE REPLACED AT 83K MILES. ALL THESE REPAIRS WERE MADE BY THE DEALERSHIP WHILE THE VEHICLE WAS UNDER WARRANTY. NO OTHER REPAIRS (TO MY KNOWLEDGE) WERE MADE TO THE ENGINE/COOLING SYSTEM. *TR
