I know this is for accords but... My 92 Civic VX has 424,550 miles on it. Original engine, 2nd transmission and 2nd clutch. I've replaced a lot of other stuff on it in the 10 years I've owned it. Body is getting rougher but I'm still getting 37mpg so I'll keep it alive.

P.S. there are a lot of "highway" miles but 3/4 of those miles are Pizza Driving miles. I can't think of a harder way to drive a car other than racing.
