Trying to help our daughter build her credit history. She bought a car and we were just going to help her pay it off but decided that it might be worth it for her to finance it instead to build up her credit. So here are my questions:

- Is this a sound approach to helping her build her credit history (by paying high interest for several payments before paying off)?
- What is the minimum amount of monthly payments she would have to make in order for it to register and have a positive impact on her credit history? The dealership said a minimum of 8 monthly payments, is that true?

TIA!
