To all the new members to this thread, welcome!!
To shed some light onto your waits: For those with OD's in March/April, that is when the massive ordering surge happened (due to gas prices). Outside of a few exceptions, you should expect to wait around 100 days for your car. This can fluctuate on a number of factors such as options, your location, cancellations, etc.
Bugging an SA will NOT get your car here sooner. Having 6 or 7 EDD's is pretty normal. Having 14 EDD's (like I did) is not.
No, the trade-in text doesn't mean a VIN is imminent.
No, there isn't a "pattern" of EDD's of 5 weeks, then 4 weeks, then 2 weeks, then 10 days. People have EDD's all over the place.
We're here to help you through this process. You're not alone. We've been there.
PS: Tesla's air conditioning suuuuuucks in very hot weather.
