I am loving Chase. I got an Auto CLI to 10,500. December I put a lot on it and made several big payments because of Christmas and some new appliances. Thank you chase for trusting me with my first 5 digit limit! Some data points:
Scores in the 660s. Opened April 2017 First auto CLI to 7500 in July. I use it as my main card so quite a bit of spending and payments. Probably around 28k a year. I don't carry a balance.
