If you're thinking about placing a deposit for a 3, keep in mind that the $7500 federal tax credit may be phased out before you get your 3 delivered. The tax credit drops to 50% in the two quarters following the sale of the 200,000th Tesla to a US customer, then to 25% in the following two quarters. Reference:
IRS Instructions for Form 8936.
Since deliveries of the 3 will likely not start until early 2018, assuming TM hits their targets for 2016 production of 80-90k vehicles (some of which are going to China and Europe), there's a very real possibility that TM will hit the 200,000 US vehicle sales sometime shortly after starting deliveries of the 3, and a lot of folks are going to be disappointed to find out that they may only get $3750 or $1875. Some are suggesting that although there will not be a "signature" 3, that highly optioned 3s will get produced first. Worst case scenario, the 3 is delayed to late 2018 and there's no credit available at all.
Good point. I think TΞSLA will (admittedly uncharacteristically) deliver the Model 3 on time. Elon is laser-focused on this goal and has reaffirmed on numerous occasions how important it was to have it release in lock-step with the gigafactory for economical reasons. Then again, it is TΞSLA and focused or not they are heading into unchartered territory with regards to volume manufacturing, and have hedged their position by also bringing TΞSLA energy on-line, which would make it a little less crucial to have Model 3 rolling out on time.
Some relevant math with regards to gmtom's post.
The 200,000 is U.S. deliveries, and thus far this is what we know:
2012 ~3k units (all U.S.)
2013 22,450 units most in U.S. (17,650)
2014 35,000 units (18,480 U.S.)
2015 50,580 units (26,566 U.S.)
2016 80k-90k projected. Assuming 55% U.S. deliveries 46,750 in U.S.
I'm not sure what will be guided for 2017, but we're sitting at 112,446 U.S. deliveries (with projected numbers for 2016) and there should be growth for 2017 so there isn't much room for Model 3 before the reductions start to occur. I'd guess about 30k-40k units if it launches on time and don't forget that it TΞSLA will still be producing Model S/X as it is rolling out the 3 in 2018.
