I’ve offered multiple solutions to your millennial friend’s problem, and all you’ve done is told me I’m wrong without offering why or a solution of your own. I’m not the troll here.
You didn’t offer solutions. You offered irrelevancies. Nothing you posted changes the simple fact that an accident that back in the day would not have totaled a car, and which could be repaired for less than $100, now costs several thousands of dollars and, if not paid, leaves one with an unusable car.
There are no two ways around that fact. You can buy as cheap a car as you want, even a $500 Craigslist special, and you can go with collision only insurance, but none of that changes the fact that if the airbags go off, you either have no car, or you have several thousands of dollars of additional expense.
All of which means that the myth of the $500 car is just that, a myth. Because you will have to set aside at least that much again to replace the car if the airbags go off. Or if any of the other required gadgets fails and requires replacement.
In short, it is significantly more expensive - over and above inflation - to own a car today, and that is an expense that most of us cannot avoid if we want to get to work on time.
So stop trolling.
