I don't live in California, taxes are less. There is no risk from a job loss, I could pay it off tomorrow. You're also only looking at one year of a several year loan.

Sure, more expensive buying a new car. But I was going to get a new car anyways, the question is loan or no loan.

I don't care too much about depreciation. It'll probably be in my garage for a decade or more so that's just paper losses today, and once again I was going to buy new anyways.
