And there was also that big push in 2009, I think, where you could trade in any sh!tbox and get a new econobox. I think this was at the time where they were pushing small econobox cars under the Obama Administration.
The US has nice things like a miniscule interest rate which makes buying new cars a lot more attractive than the 9 or 10% that the finance houses here will give you.
I see it often on Reddit as well - person goes out to buy a car, and they end up buying two instead! Imagine having the funds that you can, on a whim, decide to buy not one, but two cars. This is factoring out the BOGO offer, I'm talking just a normal straight-up purchase.
It boggles the mind probably just as much as our market boggles theirs.
