Agree with MotorDavid, to add my 2 cents try to replace fuel filter as well, as differential oil, and do the tire rotation and ballance of course, let them check ignition coils-important. Timing belt should last you longer then 30.000 miles same as spark plugs and high voltage wires. But check under the car if U live in the State with 4 seasons, snow/salt, rain etc., may cause metall corrosion. Air conditioning.
