I posted about this story in the forum olden days. My brother had a higher credit score than me, but I had a higher NW, which kind of irked me. The only difference I could see was that he had car payments. My local Credit Union was offering loans for dirt cheap. I took in my pink slip and got me a shiny car loan, with 36 equal payments.
Then a bunch of other stuff happened in very short order: I started dating a guy I'd known for a long time, and we eloped. We each sold our house for metric craptons of money to buy a very expensive new one together, for which we ended up paying cash. Oh, and I FIRE'd. By the time the dust settled, I had made payments on that car loan for about a year, so I just said "fuckit" and paid it off. I didn't care about my credit score any more.
Together, our NW has skyrocketed, but my credit score is still lower than my brother's...because he keeps buying brand-new cars. We've replaced the vehicle that I took the loan out on, but we paid cash for a used, but much newer one. It's now eight years old and we still think of it as our "new" car.
Story the second: I used to work retail commission sales in Men's Clothing. When the black Amex cards were introduced, I knew they were based on spending habits, not NW. When a customer had one of those, it told me they were status-conscious spenders and it changed the way I sold to them. They only saw the best goods, and plenty of them. Point: if you're chasing credit scores to get fancier credit cards, it could cost you in ways you'd never imagine.
IMO, beyond a certain point, chasing a higher credit score isn't worth it.
