All i know is price for a full tune up is around $400 bucks.

my car has 70 k miles on it today, I replace spark plugs, changed rear brakes and replaced all the Fluid at an auto shop. that costed me 350 already, if i want to do the full tune up, it will be more than 650 bucks.

i think only think i am missing is the air and fuel filter.. anyone know it is easy to do it myself? the manual says i should replace those filters every 30k miles.

they are charge so much that it really scare me.
