EDD is just what it says...an estimate. Owners will really only know when the get a VIN, and are contacted by a delivery advisor as to when to come in to pick up your car. Even that has some wiggle room, as the Delivery Center will do a final check over and prep prior to delivery. If they find anything amiss, they will reach out to you to reschedule. Only after final inspection will you know pretty much for sure when to schedule delivery. Then that will be on short notice, so try to remain flexible till the last moment.
