If I can get that for $200/month for a new car for 3 years then hand it back, with just known costs of insurance and gas, that's valuable. I don't care what the cost of the car is, only what the cash flow is.
Sure, I could buy a car for $5k and hope that it's cheaper over the 3 years, hope it doesn't depreciate too much, and after 25 months (plus however many months to pay for the extra maintenance and servicing included in the first car) but I'm taking the extra risk. Maybe I'll come out on top, maybe I won't.
Interest rates have been at record lows for over a decade, but the cost of the basket of goods the typical person buys hasn't changed much.
