I got a letter from Capital One Auto Finance giving me a pre-approved offer for $30,000 in auto financing at 2.9%...no sh*t, I wasn't required to give my SSN or anything and it was mine. Of course I'm not taking it since I just got a new car 5 months ago, but if they're giving me this offer, do you think they'd be willing to switch my regular Mastercard to a Platinum Visa...any thoughts? Of course I know I should just call and ask them but I wanted someone's thoughts on this before I just jump in and do it. Just wondering...
