the only thing anyone should finance is a house and no more then 15 years, I have nothing against a good credit score and yes you can save some money on some things when you open a new account ect. but thats just a hook to get you on a credit plan that most people never pay off.
I haven't financed anything seince 2000 and its been the best move of my life, There is nothing worse then being in debt, and having payments every month.
