So as I am moving towards my new Model S after the inventory debacle - I noticed that the 85D I was equipping was the same price as a P85 without some of the "nice to have" extras.
So I guess it comes down to the following: luxury vs performance.
Which version would you get with $100k budget?
Model S comparison table (range sort, from US site)
S60 208 miles range 5.9 sec 0-60 120 mph
S60D 225 miles range 5.7 sec 0-60 125 mph
S85 265 miles range 5.4 sec 0-60 125 mph
P85 265 miles range 4.2 sec 0-60 130 mph (odd duck with the lower top speed but better acceleration than the S85D)
S85D 295 miles range 5.2 sec 0-60 155 mph (king of range with no loss of top speed)
P85D 275 miles range 3.2 sec 0-60 155 mph (king of acceleration with some loss of range)
If I had all the money in the world I'd grab a S85D with tech package and 19" rims and ignore the P models entirely (85 kWh Model S $79,900, Dual Motor All Wheel Drive $4,000, Wall Connector $750, Tech Package with Autopilot $4,250, Blue Metallic Paint $750= 90,820 before $7,500 rebate, $83,320 after. oh I might spring for dual chargers or 19" cyclone wheels but I think the ~$91,000 version is close to my ideal).
If I somehow had the money for the choice my choice would be between a S60D new with tech package/autopilot ($82,820 configured as above saving $8,000) or a used S85 without tech package/autopilot (and I see some that fit that description for sale already).
in reality though I need something cheaper still, I'm looking down the road for a used S60D, used S60 or even S40, or a new Model 3. Cheapest one on autotrader that isn't a wreck is around $60,000 right now.
Honestly I don't need sub 6 second 0-60 times. I'll never push the 120MPH limit of a S60 let alone the faster speeds the others allow. I do want range but I could get by on the range of a S40, adding the range of a S60, S60D, or any flavor of 85 is just icing on the cake.
Lets see I don't need the speed, I don't need the acceleration, I don't even need the range, so what is it that makes me want a model S? Yeah it is pure electric with a battery I trust, no dealer markup/hassle, with a fast charging option I trust.
I'm happy if my Tesla is:
Able to charge at 10KW at home and >100KW at a supercharger
able to avoid battery degradation (compare Tesla vs Nissan Leaf for this one)
comes with Blue paint / Body Color Roof
has efficient tires (think 19" wheels for the S or 17" wheels for the model 3 and as narrow an aspect ratio as I can buy a good tire for it).
there is nothing on my wish list that can't be done with the cheapest model S
