<prompt> Human: I got my first credit card 6 months ago and I got my first credit score. Im trying to raise my credit score fast so that I can get a better deal on a car.

If you are looking to take out an auto loan in the very near future you should not open another card, as the hard inquiry will lower your credit score in the short term.
