Also, if you have no records, replace the brake fluid and radiator coolant.
All of the maintenance on these cars is done in miles at 7,500 intervals, except for those two items, which are done on time. They are thus usually overlooked and are very critical fluids.
The brake fluid is required to be replaced every two years and the radiator coolant is required to be replaced every three years.
