Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Took car in for oil change and tire rotation. Have prepaid oil changes up to 75000 miles from time I purchased car at which time it had 21000 miles already on it december 2007.
Told I need wiper blade, air filter and case halfs are leaking oil. altogether $4200 worth of repairs if done.
