Rusnak BMW in Los Angeles just took $5000 deposit on American Express with no transaction fee. $5000 was their limit supposedly. I plan on applying for a new card that has the best bonus the next time I get a new car, with PPF I’ll definitely reach the minimum for the bonus.
Additionally, to improve my credit, I request a CLI with all my card issuers every six months, today I got a limit increase to $35k on my Amex Blue card. When paired with little or no balance it really helps your credit utilization and for the credit bureaus to see you regularly getting approved for limit increases. Although, if the issuer wants to run a hard credit check for the increase, it’s likely not worth it.
