...or until you want a new car.
My 85 Civic's at 356,000 km (222,000 miles) and still running strong, albeit the 76hp engine does leave a lot to be desire.

I was thinking of moving up to an Accord but my Civic is one of those rare wagons and the thing is versatile like crazy, Honda just don't make good practical fuel-efficient cars anymore, just either fuel efficient and classy or practical but not fuel efficient (the gas mileage on the Element just makes me want to gag and puke) Maybe I'd go for a 4th or 5th gen Accord wagon if I can find a 5 speed version.
