They’re OK to drive and, if you get the 5.0 V10, stupidly quick. Handle like a sack of spuds, but unless you’re expecting a 4×4 to be Elise-like on the bends, you know won’t be surprised. The 3.0’s probably the best one – the 2.5’s very slow (and has Tiptronic rather than a conventional auto), and the 5.0 handles a lot worse ‘cos it’s a very heavy engine!
Typically VW drab inside, but everything works well.
Running costs aren’t terrible – the 3.0TDI auto I drove for a bit averaged 31mpg, and servicing’s OK if you go to an indy – VW will charge you £400 for a nothing-extra service. Where it can get pricey is on brake pads & discs (it’s a heavy car, and genuine VW is expensive) plus tyres. Again, nothing dramatic, but depending on the wheel size, you could easily pay £800 for a set of tyres every 20k.
Some get hit with prop shaft bearing failure (not all by any means) which is a few hundrd quid to sort at a good indy (Inde-Tech in Milton Keynes are excellent), up to £1k at VW, because they only fit an entire brand new prop shaft. Sledgehammer to crack a nut.
