Replace all fluids, filters, belts, and other consumables whose condition cannot be determined from inspection (or for which inspection indicates a need for replacement, or for which inspection involves as much work as replacement), unless you have reliable documentation on recent enough replacement (probably not if the odometer isn't working).

Inspect for leaks and other problems as noted by other replies.

Fix the odometer so that you can follow the maintenance schedule starting from when you did the above things.

If it is a wagon, verify that the tire size is correct. If the manual or labels say 185R14, make sure that the tires are that size or 195/75R14, not 185/70R14. The latter size is significantly smaller, and will cause the speedometer and odometer (if fixed) to be significantly off, and will reduce the load capacity of the car. Of course, while checking the tires, check the air pressure and condition of all tires, including the spare.
