At 130,000 miles starter motor, ignition, alternator, coil, valves, but I cannot complain for its age and mileage.
Excellent car, good to drive. Would recommend one to anyone who wants a cheap, reliable, practical vehicle for everyday use.
I'm from Portugal and I have a BX too. Sorry, but I think that it is not a everyday car because I use a lot of petrol every day!
Here in Italy we can easily put on the installation for fueling with the cheaper auto-gas: LPG (Liquefied Petroleum Gas: Propane + Butane) or Methane, and we march for long! (with Methane in the most brilliant way)
