I have a Discover card that I applied for in the mid 2000's and still have, which I've had a large balance on and paid off more than once. So I've had it for probably 10+ years at this point and I figure it must be helping, although I don't use it all that often.
I just looked at my Discover statements because they put your FICO score on there...so on my last statement where I still had some money on the card I had an 813, then the statement after I paid it off I had an 808. Ah whatever.
I currently have no loans aside from my home loan, and I do have some stuff on my paypal credit account (went a little too crazy with their 6 mo/0% financing). So, accumulate debt, make payments on time, build credit. Have any shiny new parts you want?
BTW- when I was fresh out of college all of the credit card companies had seriously killer incentives on their cards. My aforementioned Discover card gave 5% cash back on the first so many dollars worth of gas you bought every month, and I had a Capitol One card with a fixed 5.99% APR. That all went away after they passed that credit loophole act in 2008, it sucked.
