That first part wasn't directed at you, sorry if it seemed that way. Thanks for the correction. In my head I've had $4k in there for some time and was honestly confused why it was close to zero.Why are you writing all this nonsense? I just gave you a very clear case that you can easily check. Did I say that every single person lost money? Is that the argument you are trying to refute?
Also, your calculation is wrong. You do not account for the current rebate on the car.
So you agree that I'm right then
I don't agree that it was a loan. Just saying it's a weird thing to get hung up on. Regarding your net difference, yeah, you are somewhere in that 4-6k delta depending on how you want to slice and dice. Again, OP and many others like to claim 20k difference which is crazy. $5k difference for a year later for buying a 70k vehicle is not abnormal.
