I got this card about a year ago, responding to a pre-approval mailer. I was disappointed and annoyed with a starting CL of $500, with a bump to $750 after three months via credit steps.
I had tried a recon immediately after the initial approval, and the representative tried to increase the line but couldn't because there were still a couple lingering, small open collections on the CR they were viewing.
I haven't used the card that much, mostly because of the crappy credit line and I have other cards with larger limits and rewards. I have used it now and then to keep it active.
I decided to log into my account tonight, and they bumped my CL up to $2500, no request from me. My credit profile is much better than it was a year ago ... guess they must have done some sort of review. I'll take it!
It's one of my lowest CLs, but it beats my QS1 which has been sitting at $750 for almost two years. 
Auto luv with no awareness, sweeet
I'm counting the day till the new CT6 Coupe will come out.
I got one for 250, last Sat. I spoke to a rep on Wed and she informed me it would be April before my Credit steps would kick in. Came in sooner. Now its at 750 in my SD.
