My neighbor is thinking of buying car like mine but it only has 207K. The only concern is that the engine idles rough, yet as soon as you lean on the accelerator, the vibration stops immediately and the engine pulls strong and runs great. The car had no problem at all getting up to 60 mph. I was thinking maybe a motor mount, but I figured I would ask for a second opinon from here.
