Some of us need the 7 seats so MYP wasn't an option. I'd have gladly paid the extra ~$5k over MYLR if I could've.When the price difference between MY LR and MYP was $10k - $2k Boost was no brainer.
Now I would get MYP. You get a lot for $4k difference.
And I do not think Acceleration Boost will get faster, then there is no point to get MYP.
The difference in acceleration already is not that huge for average Joe.
For true fans MYP will always be much much faster then MY LR with AB.
Maybe with tax credit only for 7 seaters Tesla will now make a 7 seat MYP.
