I have had my Magna since November last year and have done 33,000 km in that time.
As per other comments, I have read, the auto transmission can be a little jerky at times, however, the dealer has tested the transmission and will be rectifying the fault by resetting the computer system on the transmission.
The majority of my driving is city based and much of it in peak hour. The car has excellent fuel economy (approx 500-550 km per tank), and has not let me down once.
The build quality, my opinion, is far superior to either Falcons or Commodores of the same age.
It was great value at $12,000 when I bought it, considering VT Commodores (which I do like!) were $14 - 15,000, and the AU Falcon (what were they thinking when they designed that body?) was about $1,000 less, generally had more mileage on them and showed their age far more.
The interior is a little on the bland side for my liking, but I can live with it.
The car has more than adequate performance, it's reliability has far exceeded my expectations, and I would deifinitely buy another one.
A much-maligned (usually, unfortunately by the misinformed) but very under-rated vehicle. Worth a drive (especially Advance or Altera for good standard equipment level) if you are considering Falcon or Commodore.
