Costs Robbo, what are the costs!
Not only that, but is there a standard configuration for trade-up units with regard to the 'optional' cards. For example, can you specify AO18 or AO08?
Also, I am having a bit of trouble reconciling the UK price of 6,500 GBP versus the presumed US price of $16K. Maybe I'm just a bit math challenged, but shouldn't the US number be more like $11K? That's expensive, sure, but it is at least a bit more palatable. I'm also interested in the comment that dealers keep the old units. Certainly suggests that there may be less dealer margin built into the upgrade price as dealers will presumably be free to sell the old units (THAT will kill private resale values).
