looking for in a motor switch? I want to replace the motor, I was offered a 2003 used neon motor, same as mine 2.0L. Now, i was told by the Junkyard that the motor had about 68000 miles but they can no longer show me the mileage on the car because car is gone and only motor is left. What should I look for in a motor replacement? how should I go about it, etc.
