As much as I hate this statement...different strokes for different folks.
I've been through the Dave Ramsey course and applied it to our lifestyle for a period of time. Despite what anyone would say about his programs and advice, the one fact is that following his guidance will not get you in trouble. Not to say that its always the best advice for you at whatever stage of life you're in, but it simply won't "get" you in trouble.
One thing to keep in mind about Dave Ramsey is that its easy for a multi-millionaire to pay cash for everything, avoid credit cards and debt. But then again, there are a great big pile multi-millionaires that have achieved their success for leveraging debt and holding cash. So what may work for you may not work for me. And that's up to you and me to work out ourselves. You'll note that over the years, good 'ole Dave has modified his positions on some issues.
For a period of time in our life, we had paid off all debt on everything except our mortgage. We were living just fine and had the things we wanted. But then when we started our construction company, things changed. As an industrial general contractor, cash is king and the sureties/banks/accountants mandate that we hold cash. That means we have to finance anything more than about $10K. Just the way it is. Other types of contractors that don't have to worry about bonding and such matters can spend out their cash, especially if they need some tax breaks.
So relevant to this thread, yes, we financed our 5er, but not because we didn't have the cash. Once size does not fit all.
