There seems to be a lot of inventory that isn't on the public website so I think you pretty much have to go through an OA to see everything. I was recently looking for a new inventory X100D and my OA was consistently finding things in his system that weren't visible on tesla.com or the community inventory sites.
Also, the "deals" they're offering right now look a lot better than they really are due to the
price drop that happened at end of August. An inventory vehicle produced before the price drop will show a higher "original price" and then a higher "discount" to bring it in line with current pricing. This is also the case for vehicles that were produced before the PUP changes were made in July; the discount will reflect the price adjustment relative to the higher prices for the previously-separate option packages.
For example, I'm currently awaiting delivery of a new inventory X 100D with ~900 miles on it. It's listed on the spec sheet as:
Model X 100D: $102,500 (not including $7500 tax credit)
Midnight silver paint: $1,000
White interior: $3,300
Enhanced autopilot: $5,000
Premium upgrades package: $6,000
Seven seat interior: $3,000
Doc/destination: $1,200
Price adjustment: ($10,700)
Total price: $111,300
However, if you price out an equivalent custom-build vehicle with the current pricing, it comes out to
$115,500, so the inventory vehicle is really only $4,200 cheaper, not $10,700 as you might think from Tesla's quoted "price adjustment". And if the inventory vehicle isn't local (mine is coming from CA to Pittsburgh) you have to add the transportation fee ($2k in my case). So, in my case I'm only saving $2,200. For me it was more about getting it sooner (early Nov. instead of late Dec/early Jan) and the couple thousand dollars I'm saving is icing on the cake.
