I ordered my Model X 100D a few months ago, and May 2nd was supposed to be the fateful day. However, I received a call on May 1st, and I was notified that the car would not be ready for delivery. There was a problem, and the service center needed to look at it. Today, I found out that there is a problem with the drive unit and that it has to be replaced. Should I accept delivery of the vehicle after the drive unit has been fixed? It is supposed to have an 8-year, infinite mile warranty, and it is being replaced, so it _should_ be fine... But I still feel uncomfortable taking delivery of a vehicle that has had major work done to it, like replacing a drive unit. Is this kind of work discoverable? Will it affect future resale value? Thanks in advance for any advice / thoughts.
