Nety: Think we owned the 323 for three years. In that time it ate two CV's and when we sold it it had a third stuffed CV. It had various engine problems mostly involving sensors and electronics. Sensor issue with the center diff lock, power window died while we were on holiday in Auckland the list would go on but it was a long time ago now. In the end I think we had experienced one two-three week period where there was nothing broken/needed doing and that is not because we drove around with things broken just that it broke as often as we could fix it.
I'm not necessarily suggesting it's true in your case, but I'm always reluctant to read too much into "I'm never going to buy another Mazda/Mitsubishi/whatever" because often the lemons are often used imports with no detailed service history. It seems unfair to blame the manufacturer if you can't be sure that the vehicle was used and maintained according to the manufacturer's specifications.
