I assume these cars rust like others. $85,000 is a lot to pay. I would drive a junker in the winter.
I just never understood spending that much money on a car.
It gets you from A to B, regardless of how much you pay for it.
The Rivian actually uses a lot of aluminum, some carbon fiber, and lots of protective coating from the factory. Not the truck for me, but it looks like that part is premium.
