I bought one new in '05.
They are only '05 and '06's in the US. Earlier than '05 is a European model.
We put 30K miles on it but unloaded it because I bought it for my wife and she hated the turbo lag and the quality issues (it would die if it got water in the Diesel and you have to open the hood and manually separate the water) and the expense/lack of availability of Diesel.
They get 26 mpg on the hwy @ 65-70 mph and 18-20 mpg in town. Once the turbo spools, they are quicker than the V6 and can tow a small trailer (5000 lbs max) pretty easily.
The quality issues are a definite negative. They have Expensive emissions controls and since there is less than 20K in the US it isn't like there is an expert on every street corner. There were some Trans problems too, due to the max torque coming at 1500 RPM.
My '05 had a 7/70 powertrain warranty (the '06's only had a 3/36) so I wasn't worried, but I'd be worried by now if I still owned it.
