Question of the day...
Polestar is having a sale. I can download 70 extra horsepower (400 -> 470) for $1,000.
I have no interest in this. Maybe if it were like $250 I would do it just for fun.
How much would you pay for 70 more horsepower?
keith@dan another way of asking is "how much would you pay for 17.5% more horsepower?"
for me, nothing. none of my cars could take advantage of it. it'd also require upgrades to (at least) the suspension and braking which in this hypothetical i don't think are included.
