My teg is 120000 mileage Ls Auto, How to prolong the car life?

Which kinds of maintainence shell I do for it?

drive it off a cliff, get the 3k insurance money and go get something else...hope this helps ;)

Change the timing belt, Water Pump, Oil, Check The Hoses, and just keep up on all the general stuff. I have a Honda Civic with 200,000 miles that runs without a hitch. :)
