I e-mailed the 1st link and no reply came.
As to why they are priced cheaper. No one in their right mind would pay $50K for a used vehicle.
Check out the prices at Kelly Blue Book, I typed in a Range Rover and it came in at just over $40K for a two year old model, that's a $35K+ hit!
I put in a 99' H1. A model came in at $45K, the seller claiming it was pristine!
I was going to buy a new H2, I think I might wait and get an 03' model (which I like better) around May/June of next year. I'd pay $30-35K no problem.
