Just got invited to configure. Ordered at 1pm 3/31 SLC store. Now the torment begins as to whether to wait for dual motor. Don't want to forego the tax credit, but, the car would be more versatile allowing me to drive up the canyons which require AWD. Also, perhaps more interior colors and options available, such as air suspension, and fewer issues with manufacturing defects. It does say I can hold my place for a dual-motor in mid-2018. Not so far away. What is latest thinking about when the full tax credit will expire.
