Today i had my 2002 aerio oil changed service. It has 57770 miles already. The auto shop is recommending the 60K mile tune-up highlighting that i need following: 1) Tune up 2) Coolant flush 3) transmission flush 4) power steering flush 5) fuel injection service a total close to $600. i don't know much of these services and i just know the basic maintenance like change oil, tire rotation, etc. is the car already due from the above services? Is the price fair enough? how much each service should cost?

i'd appreciate any tips/recommendations.

thanks!
