Ours is just over two years old now, owned it since new. Only issue we've had was a faulty check-strap on the driver's door fixed under warranty, really can't fault it.
I was about to ask the same question - my GTV Twin spark is reaching the end of its life, and the 1.9 mJet 147 looks like an absolute bargain. Has anyone had any experience in chipping the 147 diesel?
