My 1991 Metro, 4dr HB (The Silver Bullet) has 230,000 miles on it now. At 207,000, I rebuilt the engine and replaced the tranny with a JDM. After 23,000 on the rebuild, an exhaust valve has already decided to check out on me.
Oh well, at least the part I rebuilt is still going strong. Another reman head will put me in good tune again.
