That's not true. I (anyone who leased) could "afford" said car (let's say an M4) but there is no way I want to tie up that much liquid cash. Even if I was a millionaire I wouldn't buy a car with cash. Interest rates are low and even the most conservative investments should get you 5% ROI easily

I do agree it is a lower monthly than a purchase though so it is a more "affordable" way of driving the car

If I didn't like cars of course the most sense financially would be to buy a beater but where's the fun in that. also, money is only worth something when you spend it right
