It got 240,000 automatic and I bought it used. I want your option of this car? It is the first car I ever owned last this long. Also the car runs rough.

Depending on the maintenance history of the car, it might be approaching the end of its useful life.

For the rough running, have a read through this -

Well, if the only problem is that it runs rough, maybe do a tuneup... 

-plugs (check the gaps yourself!)

-wires 

-fuel filter

-clean the throttle body, intake etc. 

-clean the MAF sensor

If that doesn’t work, check for vacuum leaks. You could also have the computer scanned. 

BTW, has the PCV valve been changed?
