my shop foreman just got back from E70 training. Apparently it's really not much bigger than the E53 and the 3rd row seats is big enough for kids or topgeartom but that's about it.
only the 4.8 will be offered at first starting out at 55K and topping off in the 76-77K neighborhood. The diesel engine will NOT be making it's return to North America next year as originally planned due to differences in the fuel quality between the US and Europe. Apparently, once again, it's eating the engines
The delay puts the re-introduction to about 2009.
They should be rolling into showrooms this month. My dealer is slated to get ours in early December.
