If you want to get expensive paint or leather/interior, that will cost you more.
If you think you can do without the dual chargers and HPWC, and just use a 220V socket at home, you will save $1500 on the car, and an additional $750 which isn't part of the car itself, but a connector that you attach to the wall of your house.
I had to pay an additional $3,000 to upgrade my house to support the HPWC wall connector (plus the cost of the HPWC itself and dual chargers). This varies from house to house depending on what supply you already have available at your house, and what lengths of cable etc. electricians will have to run to install what you need. Some people pay as little as $300, or even go to Home Depot and get the parts themselves, though these are a lucky few with the right pre-existing conditions already at their houses.
No-one can see the money I spent upgrading my house, they only see the car
I recommend getting those options above, and including the HPWC, since the few times you actually have to wait while the car charges up, it can be a real pain.
The all-wheel-drive and adjustable suspension height will prove useful in rural areas, where you previously negotiated your Tahoe without worrying about whether the vehicle would scrape on the ground, or get trapped in mud, snow etc..
RE: the elistist thing... I went through that "statement of wealth" thought process a lot, and well, there is no doubt that driving around in a Tahoe conceals the fact that you can actually afford a $100K car. My previous car was an 11yr-old Civic... definitely ubiquitous. The change in cars definitely changed people's idea of what is in my bank account... but honestly, they still don't know for sure. My Tesla Model S may be my last ever car! And it could be yours, too. I had them deliver my car without the "P85" badging, so if anyone is looking who knows the difference, they can't tell it from an S60. I think you should reward yourself for what you have achieved.
Driving around a Tesla Model S actually does other people a favour too. You're not putting carbon into the atmosphere. It's pretty well-ingrained in most other nations, and just now dawning on Americans, especially those living in rural areas. In 20 years time it will be perfectly normal to consider how much carbon gets put into the atmosphere by anything+everything we do. If you choose the Tesla, you will show your neighbours that it is OK to have an electric car, that you personally took the time to consider it (instead of not thinking about it at all, and just another gas-burning car). They will know you were one of the first to understand. In these times where a lot of people seem to value protecting what they have got and reducing their accountability to others... the lone atmosphere that is shared by everyone on the planet will become an increasingly unavoidable subject of discussion, and we will come to realise that no matter how much money we have got, we can't simply do whatever we want.
Woah, coming back from the politics a bit... so, the car you're considering has been Consumer Reports' "Best Car" two years in a row so far, it's had multiple other awards, safest crash ratings from the U.S. government, and legions of existing drivers all raving about it, etc., etc. - a situation you don't see on any other car. The advantages of Tesla's all-wheel-drive system haven't had time to sink in yet but I believe their implementation is one of the best, right out of the gate. It's literally the
best car there is right now. You will NOT regret the purchase.
PLUS - your blood pressure will fall if you get this car, it's so serene and calming compared to combustion cars.
