Hmmm help decide pleaze

So i have my very first New car at 18, it is a 2015 ford fusion and i want to make my car all nice and cute but i don’t want to spend money unless i am keeping it. I have the option to keep it and pay it off (obviously), or trade it in in like a year for a different car. I really like my car but i also want a new year toyota camry. i am stuck.:( and i know if i trade it in it will lower my payments and interest rate. what do y’all think i should do? Or what would you do if i were you?
