So Trev over at M3OC claims to have some dirt...This actually sounds pretty plausible to me.
"My source, who's been very reliable in the past, has told me to "hold onto your hats" as things are about to start happening very soon and and fast.
First, the source has indeed confirmed that the initial Model 3 configurator choices are colour and wheels. No details on what those consist of but we can assume the 5 colours we've seen so far and the 2-3 wheel styles. Those choices are slated to be in place for about "3 months" while production is ramped up.
Secondly, the interior colour is to be black only during the initial phase. The wood trim found on the dash is real wood but species is unknown. The alcantara liner in the door panels is indeed making it to production. Was told the interior is very good, people are going to be happy with it. Think: fixing Model S deficiencies like door pockets, cup holder placements, arm rests, storage etc...
The best bit: July is going to surprise a lot of people and especially Wall Street, as the production line is just about ready and will start production ASAP so that several THOUSAND Model 3s are produced and stockpiled for deliveries at the end of July. This confirms what the source relayed to me back in February, namely keeping configs simple so they could make preconfigured cars instead of relying on custom configs. Later on when production ramps up in the 4th quarter more options could be added to the mix.
We may still get the token 5-6 on stage hand overs at the delivery event ceremony but Tesla is looking to really show the naysayers up this time. That's it for now"
