I'm in the 4-8 week delivery date waiting games. I've been in the habit of perusing the Tesla existing inventory each day online. Today, I did find my exact M3 configuration. Is it possible to transfer my current order to the one that matches my configuration? If so, would that put a more definitive date on my delivery? Also, what would be the usual (ballpark) time frame for delivery, coming from the already existing Tesla inventory? Also, would I still be able to take advantage of the free 1000 supercharging miles, as my current order was placed under my friend's referral link?
