Yep that may happen due to changes in CTP with regards to the car configuration - however this is a very bizzar turn of events given that cash settlement has been finalised. It would seem that there is nothing stopping Tesla from varying your final invoice/paytement figure up to the time you pick up the vehicle - which does not sound correct.Haven't gotten a car assigned yet but when I changed from RWD to LR and back to RWD it was $14 more due to CTP
