Just saw someone post that they contacted Tesla yesterday to change their AWD order color and rims which resulted in them getting delivery the same day because they had one available. Interesting thing is that the person got the same configuration as me but in AWD and is in the same region as me as well, man I could have potentially gotten delivery if I had ordered the AWD!
The most interesting thing I found with their post is that they stated that they paid the same price for the upgrades as when they had ordered so they were not subject to the $990 price increase or the $500 increase in the induction rims.
That being said, I wonder if changing from RWD to AWD will trigger the price increase of $990 or will we get the same price as when we ordered.. I don't want to take a risk for that but from several data points that I have seen, it appears that if you upgrade and get the right adviser you should be able to get the price of when you ordered. Or maybe you will get the original price that you ordered if you have the AWD at the original price and then change accessories..
