There are better (less expensive) ways to build credit than car loans.

While I don't remember the name, my wife and I built credit getting some sort of secured loan from our local credit union. The process was something along the lines of making an account with them, putting $X into the account, and then getting a 6 or 12 month loan from them for the same $X dollars at a really low interest rate. Overall I think we paid $30 to $50 dollars over that period in interest.
