And for those thinking of perhaps trading a culture that 85D in on a CPO P85D, the problem there is that the upgrade to Ludicrous supposedly only applies to the owners of P85Ds ordered or bought prior to 7/17/2015.
Again if memory serves me, someone in here inquired about having Ludicrous added to their CPO, or it may have been non CPO but pre owned, P85D and was turned down.
That makes sense too.
People would simply buy used P85Ds and add Ludicrous to them and be done with it.
Why allow someone to go out and buy a used P85D and add Ludicrous to it, when you can make them have to buy a brand new P90D with Ludicrous for the 13k up charge over a P90D which is an up charge over a used P85D in itself ?
Unless you're trying to increase revenue from your CPO sales. You could then offer to add Ludicrous to an in inventory CPO car for the 5k. Perhaps some would jump on that but you'd risk cannibalizing P90D sales, both new and Certified used, if you did it.
