buddy had a new BT50 for about 6 months when the engine gave up.. long story but he ended up with another new BT50 and so far.. so good. He likes it, he doesn't do much towing.
I have an Amarok.. love it. Would I buy again, yep in a flash. I tow a tandem stock trailer (3000kgs) no probs, fuel consumption goes up to about 12 L/100, non towing consumption around 8.5 L/100. Twin turbo 4cyl, stock, no ECU flash. Very comfy both on and offroad. Long journeys not a problem, way more comfy than my ol' 2006 Patrol, but much preferred the Patrol for serious offroad, it was manual trans, but thats being biased cause it had more scratches on it than a one armed Singaporean taxi driver with crabs.
Only thing that stinks is the VW servicing. They're lazy, expensive and do nothing beyond exactly whats written on the service sheet and for me particularly since its a 4WD I think thats piss poor. My folks also have a VW, took it too a VW dealer complaining the AC wasn't getting cold enough, received the car back with VW saying all is now good. Folks said no improvement at all, so they went to the local mechanic. He discovered the AC condenser was chockers full of bugs. $900 later! The whole front end had to come off to get to it. The ol' man fought VW and got a refund for their incompetent lazy ass servicing.
I do all my own servicing and occasionally have a good local mechanic check things over to make sure things are tickety boo.
