I’ve had enough credit cards open at once that my wallet stopped functioning as a wallet. At one point I was running eleven cards simultaneously for tradeline purposes — and the one thing that constant card management teaches you is how credit dynamics actually work. So when people ask me about the best credit card for buying a car, I have opinions. Not just about which cards have good rewards, but about what actually happens to your credit score when you put a large purchase on a card — which most guides skip over entirely.
