Sure, but if you like cars and want a brand new one, then it doesn't really matter if it's a bad or a good decision, does it? Just like buying a new phone every year is a "bad" financial decision, but it doesn't matter when that's how you want to spend your money.

What I meant was you can usually finance it and save money. There are no additional incentives for cash buyers, while you can often get incentives to finance and sub-inflation rates or even get additional incentives to finances at a higher rate.
