I bougt a new BT50 in Nov last year, can't fault it, power is good, economy is great, I have heard the clutch issues with them but a mate has a D40 and is on his second clutch and i was driving behind a D40 in bris last week with a big sticker on his back windscreen. " NOT HAPPY NISSAN, NEW CLUTCH AT 15,000KM NO WARRANTY $3500"
For the $ of the BT 50, mine was dual cab alloy tray, ladder rack, water tank and small tool box, just base model, $31k on the road, can't go wrong, and even the base model has ABS brakes.
I work on 4WD's day in day out and that is 1 reason why I went the BT, plus I didn't need a mega $$ ute as i've got our GU for long distance stuff.
