My last car had just got up to 100,000 miles, and I was wondering just what the life expectancy of a z engine was. Who has racked up the most miles here, or at least has bought a high-miler?

 

I have heard people say the car gets a bit 'leggy' or tired, or whatever, but what actually happens to a high milage engine? and what can you do to repair an ancient motor?

 

When does a z really begin to show it's age?

there was a NA zed in the US that had 350k on the clock with the origonal engine. Obviously the turbo engine has a much shorter lifespan but there are some on here with the best part of 200k on the clock and are only just starting to have problems.
