You could get the recommended thirty thousand mile service information and slowly do the proceedure yourself. Probably lists many items to check for wear etc.
These services were primarily intended to keep reliability up I believe. Also great way to learn about many areas of the car as you check them.
Possibly will also list a lot of things like lubricating your door and hood hinges, cleaning and lubrication of sunroof mechanisim and feeder cable as well for example, checking out belts, flushing the brake and power steering system, treating your doors weatherstripping, checking your voltage regulator for remaining brush length, checking brake pads, suspension, steering, and things like shocks for leaking or wear. I have never seen the list myself but it does exist.
I believe the valve clearances on your model are to be checked every fifteen thousand as well for example. Especially if you do not have any knowledge of when last checked they might be really overdue. Less chance of damaging a valve in the engine to keep on top of this stuff. After the first time it is a piece of cake so to speak.
This is real preventative maintenance at it's best and you can do it in stages. More time intensive than financially driven as well.
