What should I expect in terms of financing a used 5'er?

I guess it all depends on a person's situation. I do agree that if a 5er is about the price of a new car, one should be able to pay that off in 5 years. Not too many people have that kind of cash saved up.

There can be situations where a person may have to suddenly become a fulltimer for some reason and do not have the time to save up for years.
