I currently have a 703 at a “thin credit file.” My oldest card is my discover it, with an age of 11 months, I was looking to get into the Chase freedom unlimited, mainly for the intro offer, but from the research I’ve done, I need a minimum of 1 year age on my credit profile, could anyone back this?
Besides that, I was wondering if anyone has their own tips and overall advice of where I can take my credit profile from here!
Currently standing at 4 cards with a combined limit of 9k

Got my first car at 18, always been into cars, didn’t want to get in no civic. It may be a little humble car but it’s definitely fun! It’s been a year with the car, nothing major has went wrong, at 127k miles now. Do you guys have any advice about this car specifically, maintenance wise, or even tuning? I’d appreciate the input less
