So hopefully my experience can help some here.
Picked up my P on Thursday, sold my SR on Friday.
The SR was so cheap, and its weight, and rwd made it fun.
Couldn't pull the trigger on my early LR reservation because the car just feels boaty. (Probably will not exercise that reservation.)
Would love to drive Y with boost. I do have a LR with 3 rows reserved and am waiting on that one for an Austin car.
(P arrived thursday, SR left friday, 3 staying... forever?)
LOVED the SR. Almost as fast as LR, lighter, lot less money. Drove it 12k in 5 months, and sold it for $5k more than I paid (and 18k more than Tesla offered) because towing bicycles it was always charging, and I'd like to not stop to charge 2x to get to the Adirondacks. Also, this is such a great road trip car I'd like to take a trip to Moab.
So the P is a beast. I agree with all the comments about wheels and tires, and pushed on this car when it showed up a month early last winter, right in the middle of a polar vortex. I like my 3 acceleration. If boost makes the LR close to that, I'll probably be OK moving to LR with boost.
BTW, Cars now come with bioweapon mode.
ON FSD:
Think you don't need FSD? Ok.
I have FSD on my 3 and missed it on my SRY, but the option depreciates like a stone so not putting it on anything I might not be keeping.
I love FSD, and LOVE the subscription option as I'm likely to use that every summer on the P. $600 a year? SOLD!
