I bought the car in 2003 with 70000.
I now has 282000 miles on it and still runs good.
Original clutch and no major repairs of any kind.
The only problems was front spring which was recall and some electrical harness issues due to salt spray.
Other than this just wear and tear items normal with putting lots of miles on a car.
I have looked at and rented the 2nd and 3rd Gen Focus and they just do not compare to how good the 1st Gen is.
Reliability and great gas mileage.
Excellent manual transmission
Better corrosion prevention on rocker panel and spray shield to protect firewall area.
