And things are weighted differently between the three. Also, when you go to apply for an auto loan they may use a different model where it puts emphasis on previous car loans. There are so many variables it’s hard to really compare.
Biggest things I’ve noticed are having a huge availability in your card lines is good (I have about 100k in available credit) and a very low usage ratio. <10% although if you want the magic of an 850 it has to be under 1%
Add that to length of credit history (27 years for me) and of course paying payments on time and having a variety of debt. (Credit cards, car, house). I find my daughters credit is far more volatile than mine due to her shorter credit history.
