The Dark Ash Wood trim that I will be paying $750 for is now no charge and the formerly no charge Matte Obeche Wood trim is $750 on the Design Studio. Other changes include $200 for the accessory hitch instead of no charge and the High Amperage Charger Upgrade has gone from $1000 to $1500. Do I have any recourse with the price drop on the trim or is the price at configuration time the final price?
