upgradability of electric cars

if electric cars are redesigned 

so that it becomes easier and cheaper to replace components 

then that could increase the second hand value of those electric cars 

so that the buyer of a new electric car 

would know that he at a later time could sell it at a good price 

in the second hand market 

which will make it more attractive for people to buy new electric cars

but according to gemini ai 

it would be difficult to redesign electric cars 

so that it would become easy and cheap 

to replace the big battery in the floor of the electric car 

since it's a structural part of the electric car 

an old electric car bought on the second hand market 

could be upgraded 

by replacing the big batteries in the floor 

so that the old electric car would get better performance 

than what it had when it was new 

but replacing the big batteries in the floor of an electric car 

is currently quite expensive 

because of the current design of electric cars
