He could have all debts paid and $500,000 in the bank. In which case he should still buy it used just because of the principle of it? I've listened to a lot of Dave Ramsey and admittedly do not agree with everything he say. If a guy is rich then why must he live like the millionaire next door, never lease, or still buy used?
Of course you would disagree with someone leasing or making payments on anything, but as explained onthe original post, sometimes leasing makes more sense and people choose that route even if it involves payments. My parents had cash to buy their new 4runner and got a promotional rate of 0%. So her car payment was over $1,000 a month, but she still had an extra $30,000+ earning 5% interest for 3 years. Could she afford the new car, yes. But she still did payments and ended up earning some money on the cash rather than dumping it in the car.
I realize you would never do this. But the fact that you have to jump in on every financial post and tell everyone how stupid they are hurts your chances of anyone seriously listening to your opinion.
