I reserved a M3 27 months ago and received an invitation to design a model five days ago. The designer indicates that I am eligible to receive a $7,500 Federal tax credit. However, my understanding is that I will only be eligible for that amount if 1) Tesla hit the 200k mark after 01 April, and 2) I register my new M3 before 30 September. Are early registers guaranteed to receive their car prior to 30 September if they order now? If I can get the full tax credit, I will order now. Otherwise, I'll wait until they sell the standard battery $35K model.
