ive used and abused mine wrecked it a few times, rally raced, and off roaded with it. 300K + miles still original clutch, timing belt. the only thing i do is change the oil and tires when they wear out. this lil car refuses to die.
This '64 Mercury has over 557K on the original motor. The 91+ yr old female owner took a 3200 mile trip in it 2 years ago. By herself.
Funny story how she always bought parts with lifetime guarantee knowing she was going to keep the car a long time. She has gotten a lot of replacement parts on those deals.
